Inheritance diagram for Model:

Detailed Description

An SBML model.

In an SBML model definition, a single object of class Model serves as the overall container for the lists of the various model components. All of the lists are optional, but if a given list container is present within the model, the list must not be empty; that is, it must have length one or more. The following are the components and lists permitted in different Levels and Versions of SBML in version 5.18.0 of libSBML:

In SBML Level 1, the components are: UnitDefinition, Compartment, Species, Parameter, Rule, and Reaction. Instances of the classes are placed inside instances of classes ListOfUnitDefinitions, ListOfCompartments, ListOfSpecies, ListOfParameters, ListOfRules, and ListOfReactions.
In SBML Level 2 Version 1, the components are: FunctionDefinition, UnitDefinition, Compartment, Species, Parameter, Rule, Reaction and Event. Instances of the classes are placed inside instances of classes ListOfFunctionDefinitions, ListOfUnitDefinitions, ListOfCompartments, ListOfSpecies, ListOfParameters, ListOfRules, ListOfReactions, and ListOfEvents.
In SBML Level 2 Versions 2, 3 and 4, the components are: FunctionDefinition, UnitDefinition, CompartmentType, SpeciesType, Compartment, Species, Parameter, InitialAssignment, Rule, Constraint, Reaction and Event. Instances of the classes are placed inside instances of classes ListOfFunctionDefinitions, ListOfUnitDefinitions, ListOfCompartmentTypes, ListOfSpeciesTypes, ListOfCompartments, ListOfSpecies, ListOfParameters, ListOfInitialAssignments, ListOfRules, ListOfConstraints, ListOfReactions, and ListOfEvents.
In SBML Level 3 Version 1, the components are: FunctionDefinition, UnitDefinition, Compartment, Species, Parameter, InitialAssignment, Rule, Constraint, Reaction and Event. Instances of the classes are placed inside instances of classes ListOfFunctionDefinitions, ListOfUnitDefinitions, ListOfCompartments, ListOfSpecies, ListOfParameters, ListOfInitialAssignments, ListOfRules, ListOfConstraints, ListOfReactions, and ListOfEvents.

Although all the lists are optional, there are dependencies between SBML components such that defining some components requires defining others. An example is that defining a species requires defining a compartment, and defining a reaction requires defining a species. The dependencies are explained in more detail in the SBML specifications.

In addition to the above lists and attributes, the Model class in both SBML Level 2 and Level 3 has the usual two attributes of "id" and "name", and both are optional. As is the case for other SBML components with "id" and "name" attributes, they must be used according to the guidelines described in the SBML specifications. (Within the frameworks of SBML Level 2 and Level 3, a Model object identifier has no assigned meaning, but extension packages planned for SBML Level 3 are likely to make use of this identifier.)

Finally, SBML Level 3 has introduced a number of additional Model attributes. They are discussed in a separate section below.

Approaches to creating objects using the libSBML API

LibSBML provides two main mechanisms for creating objects: class constructors (e.g., Species::Species() ), and createObject() methods (such as Model::createSpecies()) provided by certain Object classes such as Model. These multiple mechanisms are provided by libSBML for flexibility and to support different use-cases, but they also have different implications for the overall model structure.

In general, the recommended approach is to use the createObject() methods. These methods both create an object and link it to the parent in one step. Here is an example:

// Create an SBMLDocument object in Level 3 Version 1 format:
SBMLDocument* sbmlDoc = new SBMLDocument(3, 1);
// Create a Model object inside the SBMLDocument object and set
// its identifier.  The call returns a pointer to the Model object
// created, and methods called on that object affect the attributes
// of the object attached to the model (as expected).
Model* model = sbmlDoc->createModel();
model->setId("BestModelEver");
// Create a Species object inside the Model and set its identifier.
// Similar to the lines above, this call returns a pointer to the Species
// object created, and methods called on that object affect the attributes
// of the object attached to the model (as expected).
Species *sp = model->createSpecies();
sp->setId("MySpecies");

The createObject() methods return a pointer to the object created, but they also add the object to the relevant list of object instances contained in the parent. (These lists become the <listOfObjects> elements in the finished XML rendition of SBML.) In the example above, Model::createSpecies() adds the created species directly to the <listOfSpecies> list in the model. Subsequently, methods called on the species change the species in the model (which is what is expected in most situations).

Consistency and adherence to SBML specifications

To make it easier for applications to do whatever they need, libSBML version 5.18.0 is relatively lax when it comes to enforcing correctness and completeness of models during model construction and editing. Essentially, libSBML will not in most cases check automatically that a model's components have valid attribute values, or that the overall model is consistent and free of errors—even obvious errors such as duplication of identifiers. This allows applications great leeway in how they build their models, but it means that software authors must take deliberate steps to ensure that the model will be, in the end, valid SBML. These steps include such things as keeping track of the identifiers used in a model, manually performing updates in certain situations where an entity is referenced in more than one place (e.g., a species that is referenced by multiple SpeciesReference objects), and so on.

That said, libSBML does provide powerful features for deliberately performing validation of SBML when an application decides it is time to do so. The interfaces to these facilities are on the SBMLDocument class, in the form of SBMLDocument::checkInternalConsistency() and SBMLDocument::checkConsistency(). Please refer to the documentation for SBMLDocument for more information about this.

While applications may play fast and loose and live like free spirits during the construction and editing of SBML models, they should always make sure to call SBMLDocument::checkInternalConsistency() and/or SBMLDocument::checkConsistency() before writing out the final version of an SBML model.

Model attributes introduced in SBML Level 3

As mentioned above, the Model class has a number of optional attributes in SBML Level 3. These are "substanceUnits", "timeUnits", "volumeUnits", "areaUnits", "lengthUnits", "extentUnits", and "conversionFactor. The following provide more information about them.

The "substanceUnits" attribute

The "substanceUnits" attribute is used to specify the unit of measurement associated with substance quantities of Species objects that do not specify units explicitly. If a given Species object definition does not specify its unit of substance quantity via the "substanceUnits" attribute on the Species object instance, then that species inherits the value of the Model "substanceUnits" attribute. If the Model does not define a value for this attribute, then there is no unit to inherit, and all species that do not specify individual "substanceUnits" attribute values then have no declared units for their quantities. The SBML Level 3 specifications provide more details.

Note that when the identifier of a species appears in a model's mathematical expressions, the unit of measurement associated with that identifier is not solely determined by setting "substanceUnits" on Model or Species. Please see the discussion about units given in the documentation for the Species class.

The "timeUnits" attribute

The "timeUnits" attribute on SBML Level 3's Model object is used to specify the unit in which time is measured in the model. This attribute on Model is the only way to specify a unit for time in a model. It is a global attribute; time is measured in the model everywhere in the same way. This is particularly relevant to Reaction and RateRule objects in a model: all Reaction and RateRule objects in SBML define per-time values, and the unit of time is given by the "timeUnits" attribute on the Model object instance. If the Model "timeUnits" attribute has no value, it means that the unit of time is not defined for the model's reactions and rate rules. Leaving it unspecified in an SBML model does not result in an invalid model in SBML Level 3; however, as a matter of best practice, we strongly recommend that all models specify units of measurement for time.

The "volumeUnits", "areaUnits", and "lengthUnits" attributes

The attributes "volumeUnits", "areaUnits" and "lengthUnits" together are used to set the units of measurements for the sizes of Compartment objects in an SBML Level 3 model when those objects do not otherwise specify units. The three attributes correspond to the most common cases of compartment dimensions: "volumeUnits" for compartments having a "spatialDimensions" attribute value of "3", "areaUnits" for compartments having a "spatialDimensions" attribute value of "2", and "lengthUnits" for compartments having a "spatialDimensions" attribute value of "1". The attributes are not applicable to compartments whose "spatialDimensions" attribute values are not one of "1", "2" or "3".

If a given Compartment object instance does not provide a value for its "units" attribute, then the unit of measurement of that compartment's size is inherited from the value specified by the Model "volumeUnits", "areaUnits" or "lengthUnits" attribute, as appropriate based on the Compartment object's "spatialDimensions" attribute value. If the Model object does not define the relevant attribute, then there are no units to inherit, and all Compartment objects that do not set a value for their "units" attribute then have no units associated with their compartment sizes.

The use of three separate attributes is a carry-over from SBML Level 2. Note that it is entirely possible for a model to define a value for two or more of the attributes "volumeUnits", "areaUnits" and "lengthUnits" simultaneously, because SBML models may contain compartments with different numbers of dimensions.

The "extentUnits" attribute

Reactions are processes that occur over time. These processes involve events of some sort, where a single ``reaction event'' is one in which some set of entities (known as reactants, products and modifiers in SBML) interact, once. The extent of a reaction is a measure of how many times the reaction has occurred, while the time derivative of the extent gives the instantaneous rate at which the reaction is occurring. Thus, what is colloquially referred to as the "rate of the reaction" is in fact equal to the rate of change of reaction extent.

In SBML Level 3, the combination of "extentUnits" and "timeUnits" defines the units of kinetic laws in SBML and establishes how the numerical value of each KineticLaw object's mathematical formula is meant to be interpreted in a model. The units of the kinetic laws are taken to be "extentUnits" divided by "timeUnits".

Note that this embodies an important principle in SBML Level 3 models: all reactions in an SBML model must have the same units for the rate of change of extent. In other words, the units of all reaction rates in the model must be the same. There is only one global value for "extentUnits" and one global value for "timeUnits".

The "conversionFactor" attribute

The attribute "conversionFactor" in SBML Level 3's Model object defines a global value inherited by all Species object instances that do not define separate values for their "conversionFactor" attributes. The value of this attribute must refer to a Parameter object instance defined in the model. The Parameter object in question must be a constant; ie it must have its "constant" attribute value set to "true".

If a given Species object definition does not specify a conversion factor via the "conversionFactor" attribute on Species, then the species inherits the conversion factor specified by the Model "conversionFactor" attribute. If the Model does not define a value for this attribute, then there is no conversion factor to inherit. More information about conversion factors is provided in the SBML Level 3 specifications.

Constructor & Destructor Documentation

Model::Model	(	unsigned int	level,
		unsigned int	version
	)

Creates a new Model using the given SBML level and version values.

Parameters

level	an unsigned int, the SBML Level to assign to this Model.
version	an unsigned int, the SBML Version to assign to this Model.

Exceptions

SBMLConstructorException Thrown if the given level and version combination are invalid or if this object is incompatible with the given level and version.

Note: Attempting to add an object to an SBMLDocument having a different combination of SBML Level, Version and XML namespaces than the object itself will result in an error at the time a caller attempts to make the addition. A parent object must have compatible Level, Version and XML namespaces. (Strictly speaking, a parent may also have more XML namespaces than a child, but the reverse is not permitted.) The restriction is necessary to ensure that an SBML model has a consistent overall structure. This requires callers to manage their objects carefully, but the benefit is increased flexibility in how models can be created by permitting callers to create objects bottom-up if desired. In situations where objects are not yet attached to parents (e.g., SBMLDocument), knowledge of the intented SBML Level and Version help libSBML determine such things as whether it is valid to assign a particular value to an attribute.

Model::Model ( SBMLNamespaces * sbmlns )

Creates a new Model using the given SBMLNamespaces object sbmlns.

: The SBMLNamespaces object encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and (in Level 3) packages used in addition to SBML Level 3 Core. A common approach to using libSBML's SBMLNamespaces facilities is to create an SBMLNamespaces object somewhere in a program once, then hand that object as needed to object constructors that accept SBMLNamespaces as arguments.

Parameters

sbmlns an SBMLNamespaces object.

Exceptions

SBMLConstructorException Thrown if the given sbmlns is inconsistent or incompatible with this object.

Note: Attempting to add an object to an SBMLDocument having a different combination of SBML Level, Version and XML namespaces than the object itself will result in an error at the time a caller attempts to make the addition. A parent object must have compatible Level, Version and XML namespaces. (Strictly speaking, a parent may also have more XML namespaces than a child, but the reverse is not permitted.) The restriction is necessary to ensure that an SBML model has a consistent overall structure. This requires callers to manage their objects carefully, but the benefit is increased flexibility in how models can be created by permitting callers to create objects bottom-up if desired. In situations where objects are not yet attached to parents (e.g., SBMLDocument), knowledge of the intented SBML Level and Version help libSBML determine such things as whether it is valid to assign a particular value to an attribute.

Model::~Model ( )

virtual

Destroys this Model.

Model::Model ( const Model & orig )

Copy constructor; creates a (deep) copy of the given Model object.

Parameters

orig	the object to copy.

Member Function Documentation

int Model::addCompartment ( const Compartment * c )

Adds a copy of the given Compartment object to this Model.

Parameters

c	the Compartment object to add.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

Note: This method should be used with some caution. The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained inside this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance in this object. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result. Please see other methods on this class (particularly a corresponding method whose name begins with the word create) for alternatives that do not lead to these issues.

See also: createCompartment()

int Model::addCompartmentType ( const CompartmentType * ct )

Adds a copy of the given CompartmentType object to this Model.

Parameters

ct	the CompartmentType object to add.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

Note: This method should be used with some caution. The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained inside this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance in this object. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result. Please see other methods on this class (particularly a corresponding method whose name begins with the word create) for alternatives that do not lead to these issues.; The CompartmentType object class is only available in SBML Level 2 Versions 2–4. It is not available in Level 1 nor Level 3.

int Model::addConstraint ( const Constraint * c )

Adds a copy of the given Constraint object to this Model.

Parameters

c	the Constraint object to add.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

Note: This method should be used with some caution. The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained inside this object.

int SBase::addCVTerm	(	CVTerm *	term,
		bool	newBag = `false`
	)

inherited

Adds a copy of the given CVTerm object to this SBML object.

Parameters

term	the CVTerm to assign.
newBag	if `true`, creates a new RDF bag with the same identifier as a previous bag, and if `false`, adds the term to an existing RDF bag with the same type of qualifier as the term being added.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

LIBSBML_OPERATION_SUCCESS
LIBSBML_OPERATION_FAILED
LIBSBML_UNEXPECTED_ATTRIBUTE, if this object lacks a "metaid" attribute
LIBSBML_INVALID_OBJECT

Note: Since the CV Term uses the "metaid" attribute of the object as a reference, if the object has no "metaid" attribute value set, then the CVTerm will not be added.; This method should be used with some caution. The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained inside this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance in this object. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result.

ia	the InitialAssignment object to add.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

Note: This method should be used with some caution. The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained inside this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance in this object. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result. Please see other methods on this class (particularly a corresponding method whose name begins with the word create) for alternatives that do not lead to these issues.

This method also calls the appendFrom method on all libSBML plug-in objects.

: SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.

Parameters

model the Model to merge with this one.

int SBase::appendNotes ( const XMLNode * notes )

inherited

Appends the given notes to the "notes" subelement of this object.

The content of notes is copied.

The optional SBML element named "notes", present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.

The format of "notes" elements must be XHTML 1.0. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

Parameters

notes an XML node structure that is to appended to the content of the "notes" subelement of this object.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

: If a plugin is disabled, the package information it contains is no longer considered to be part of the SBML document for the purposes of searching the document or writing out the document. However, the information is still retained, so if the plugin is enabled again, the same information will once again be available, and will be written out to the final model.

Parameters

recursive if true, the disabled information will be deleted also from all child elements, otherwise only from this SBase element.

int SBase::disablePackage	(	const std::string &	pkgURI,
		const std::string &	pkgPrefix
	)

inherited

Disables the given SBML Level 3 package on this object.

This method disables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object.

An example of when this may be useful is during construction of model components when mixing existing and new models. Suppose your application read an SBML document containing a model that used the SBML Hierarchical Model Composition (“comp”) package, and extracted parts of that model in order to construct a new model in memory. The new, in-memory model will not accept a component drawn from an other SBMLDocument with different package namespace declarations. You could reconstruct the same namespaces in the in-memory model first, but as a shortcut, you could also disable the package namespace on the object being added. Here is a code example to help clarify this:

// We read in an SBML L3V1 model that uses the 'comp'
// package namespace.
doc = readSBML("sbml-file-with-comp-elements.xml");
// We extract one of the species from the model.
Species* s1 = doc->getModel()->getSpecies(0);
// We construct a new model.  This model does not use the
// 'comp' package.
Model * newModel = new Model(3,1);
// The following will fail with an error, because addSpecies()
// will first check that the parent of the given object has
// namespaces declared, and will discover that s1 does but
// newModel does not.
// newModel->addSpecies(s1);
// However, if we disable the 'comp' package on s1, then
// the call to addSpecies will work.
s1->disablePackage("http://www.sbml.org/sbml/level3/version1/comp/version1",
                   "comp");
newModel->addSpecies(s1);

Parameters

pkgURI	the URI of the package.
pkgPrefix	the XML prefix of the package.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

See also: enablePackage(const std::string& pkgURI, const std::string& pkgPrefix, bool flag)

int SBase::enablePackage	(	const std::string &	pkgURI,
		const std::string &	pkgPrefix,
		bool	flag
	)

inherited

Enables or disables the given SBML Level 3 package on this object.

This method enables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object. This method is the converse of SBase::disablePackage(const std::string& pkgURI, const std::string& pkgPrefix).

Parameters

pkgURI	the URI of the package.
pkgPrefix	the XML prefix of the package.
flag	whether to enable (`true`) or disable (`false`) the package.

List * Model::getAllElements ( ElementFilter * filter = NULL )

virtual

Returns a List of all child objects.

This returns all child objects nested to an arbitrary depth. If an optional element filter is provided, only those objects for which the filter's filter() method returns true will be added to the list.

Parameters

filter a pointer to an ElementFilter, which causes the function to return only elements that match a particular set of constraints. If NULL (the default), the function will return all child objects.

Returns: a List of pointers to all children objects.

Reimplemented from SBase.

This method searches the tree of objects that are parents of this object, and returns the first one that has the given SBML type code from the given pkgName.

Parameters

type	the SBML type code of the object sought.
pkgName	(optional) the short name of an SBML Level 3 package to which the sought-after object must belong.

Returns: the ancestor SBML object of this SBML object that corresponds to the given SBMLTypeCode_t value, or NULL if no ancestor exists.

Warning: The optional argument pkgName must be used for all type codes from SBML Level 3 packages. Otherwise, the function will search the "core" namespace alone, not find any corresponding elements, and return NULL.

XMLNode * SBase::getAnnotation ( )

inherited

Returns the content of the "annotation" subelement of this object as a tree of XMLNode objects.

: Whereas the SBML "notes" subelement is a container for content to be shown directly to humans, the "annotation" element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for "annotation". The element's content type is XML type "any", allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

The annotations returned by this method will be in XML form. LibSBML provides an object model and related interfaces for certain specific kinds of annotations, namely model history information and RDF content. See the ModelHistory, CVTerm and RDFAnnotationParser classes for more information about the facilities available.

Returns: the annotation of this SBML object as a tree of XMLNode objects.

unsigned int SBase::getColumn ( ) const

inherited

Returns the column number where this object first appears in the XML representation of the SBML document.

Returns: the column number of this SBML object. If this object was created programmatically and not read from a file, this method will return the value 0.

Note: The column number for each construct in an SBML model is set upon reading the model. The accuracy of the column number depends on the correctness of the XML representation of the model, and on the particular XML parser library being used. The former limitation relates to the following problem: if the model is actually invalid XML, then the parser may not be able to interpret the data correctly and consequently may not be able to establish the real column number. The latter limitation is simply that different parsers seem to have their own accuracy limitations, and out of all the parsers supported by libSBML, none have been 100% accurate in all situations. (At this time, libSBML supports the use of libxml2, Expat and Xerces.)

SBasePlugin * SBase::getDisabledPlugin ( unsigned int n )

inherited

Returns the nth disabled plug-in object (extension interface) for an SBML Level 3 package extension.

If no such plugin exists, NULL is returned.

: SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.

: If a plugin is disabled, the package information it contains is no longer considered to be part of the SBML document for the purposes of searching the document or writing out the document. However, the information is still retained, so if the plugin is enabled again, the same information will once again be available, and will be written out to the final model.

Parameters

n	the index of the disabled plug-in to return.

Returns: the nth disabled plug-in object (the libSBML extension interface) of a package extension. If the index n is invalid, NULL is returned.

const SBase * SBase::getElementByMetaId ( const std::string & metaid ) const

inherited

Returns the first child element it can find with a specific "metaid" attribute value, or NULL if no such object is found.

: The optional attribute named "metaid", present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each "metaid" value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the "metaid" attribute used by SBML—something to be aware of if your application-specific XML content inside the "annotation" subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the "metaid" attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the "annotation" subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

Parameters

metaid string representing the "metaid" attribute value of the object to find.

Returns: pointer to the first element found with the given meta-identifier.

SBase * Model::getElementByMetaId ( const std::string & metaid )

virtual const std::string& Model::getId ( ) const

virtual

Returns the value of the "id" attribute of this Model.

Note: Because of the inconsistent behavior of this function with respect to assignments and rules, it is now recommended to use the getIdAttribute() function instead.

The identifier given by an object's "id" attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of "id" is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:

     letter ::= 'a'..'z','A'..'Z'
     digit  ::= '0'..'9'
     idChar ::= letter | digit | '_'
     SId    ::= ( letter | '_' ) idChar*

The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined "id" and "name" attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have "id" or "name" attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: "variable" (for the rules and event assignments), "symbol" (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.

With the addition of "id" and "name" attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original "id" methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual "id" attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an "id" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write "id" attributes for those objects.

Returns: the id of this Model.

Reimplemented from SBase.

Examples:: createExampleSBML.cpp, printSBML.cpp, and SBMLHttpResolverExample.cpp.

inherited

Returns the SBML Level of the SBMLDocument object containing this object.

: LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)

Note: The line number for each construct in an SBML model is set upon reading the model. The accuracy of the line number depends on the correctness of the XML representation of the model, and on the particular XML parser library being used. The former limitation relates to the following problem: if the model is actually invalid XML, then the parser may not be able to interpret the data correctly and consequently may not be able to establish the real line number. The latter limitation is simply that different parsers seem to have their own accuracy limitations, and out of all the parsers supported by libSBML, none have been 100% accurate in all situations. (At this time, libSBML supports the use of libxml2, Expat and Xerces.)

const string & SBase::getMetaId ( ) const

inherited

Returns the value of the "metaid" attribute of this SBML object.

: The optional attribute named "metaid", present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each "metaid" value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the "metaid" attribute used by SBML—something to be aware of if your application-specific XML content inside the "annotation" subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the "metaid" attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the "annotation" subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

Returns: the meta-identifier of this SBML object.

const string & Model::getName ( ) const

virtual

Returns the value of the "name" attribute of this Model object.

: In SBML Level 3 Version 2, the "id" and "name" attributes were moved to SBase directly, instead of being defined individually for many (but not all) objects. LibSBML has for a long time provided functions defined on SBase itself to get, set, and unset those attributes, which would fail or otherwise return empty strings if executed on any object for which those attributes were not defined. Now that all SBase objects define those attributes, those functions now succeed for any object with the appropriate level and version.

The "name" attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of "name" is the type string defined in XML Schema. SBML imposes no restrictions as to the content of "name" attributes beyond those restrictions defined by the string type in XML Schema.

The recommended practice for handling "name" is as follows. If a software tool has the capability for displaying the content of "name" attributes, it should display this content to the user as a component's label instead of the component's "id". If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the "name" attribute is missing on a given component, then the user interface should display the value of the "id" attribute instead. (Script language interpreters are especially likely to display "id" instead of "name".)

As a consequence of the above, authors of systems that automatically generate the values of "id" attributes should be aware some systems may display the "id"'s to the user. Authors therefore may wish to take some care to have their software create "id" values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the "id" attribute be an abbreviated form of the name attribute value.

An additional point worth mentioning is although there are restrictions on the uniqueness of "id" values, there are no restrictions on the uniqueness of "name" values in a model. This allows software applications leeway in assigning component identifiers.

Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a "name" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write "name" attributes for those objects.

Returns: the name of this SBML object, or the empty string if not set or unsettable.

XMLNode * SBase::getNotes ( )

inherited

Returns the content of the "notes" subelement of this object as a tree of XMLNode objects.

: The optional SBML element named "notes", present on every major SBML component type (and in SBML Level 3, the "message" subelement of Constraint), is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.

The format of "notes" elements conform to the definition of XHTML 1.0. However, the content cannot be entirely free-form; it must satisfy certain requirements defined in the SBML specifications for specific SBML Levels. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); this method implements a verification process that lets callers check whether the content of a given XMLNode object conforms to the SBML requirements for "notes" and "message" structure. Developers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations of using "notes" in SBML. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

The "notes" element content returned by this method will be in XML form, but libSBML does not provide an object model specifically for the content of notes. Callers will need to traverse the XML tree structure using the facilities available on XMLNode and related objects. For an alternative method of accessing the notes, see getNotesString().

Returns: the content of the "notes" subelement of this SBML object as a tree structure composed of XMLNode objects.

: SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages.

LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.

Parameters

package the name or URI of the package.

Returns: the plug-in object (the libSBML extension interface) of a package extension with the given package name or URI.

The returned plug-in will be the appropriate type of plugin requested: calling Model::getPlugin("fbc") will return an FbcModelPlugin; calling Parameter::getPlugin("comp") will return CompSBasePlugin, etc.

If no such plugin exists, NULL is returned.

BiolQualifierType_t SBase::getResourceBiologicalQualifier ( std::string resource )

inherited

Returns the MIRIAM biological qualifier associated with the given resource.

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include "is" and "has part", but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using values from the enumeration type BiolQualifierType_t.

This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a value from the enumeration type BiolQualifierType_t.

Parameters

resource string representing the resource; e.g., "http://www.geneontology.org/#GO:0005892".

Returns: the qualifier associated with the resource, or BQB_UNKNOWN if the resource does not exist.

Note: The set of MIRIAM biological qualifiers grows over time, although relatively slowly. The values in the enumeration BiolQualifierType_t are up to date with MIRIAM at the time of a given libSBML release. The set of values may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.

ModelQualifierType_t SBase::getResourceModelQualifier ( std::string resource )

inherited

Returns the MIRIAM model qualifier associated with the given resource.

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object. An example qualifier is "isDerivedFrom", to indicate that a given component of the model is derived from the modeling object represented by the referenced resource. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify model annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM model qualifiers are represented using values from the enumeration type ModelQualifierType_t.

This method method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have model qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of type of model qualifier associated with that resource as a value from the enumeration type ModelQualifierType_t.

Parameters

resource string representing the resource; e.g., "http://www.geneontology.org/#GO:0005892".

Returns: the ModelQualifierType_t value associated with the resource, or BQM_UNKNOWN if the resource does not exist.

Note: The set of MIRIAM biological qualifiers grows over time, although relatively slowly. The values in the enumeration ModelQualifierType_t are up to date with MIRIAM at the time of a given libSBML release. The set of values may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.

const SBMLDocument * SBase::getSBMLDocument ( ) const

inherited

Returns the SBMLDocument object containing this object instance.

: LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)

This method allows the caller to obtain the SBMLDocument for the current object.

Returns: the parent SBMLDocument object of this SBML object.

int SBase::getSBOTerm ( ) const

inherited

Returns the integer portion of the value of the "sboTerm" attribute of this object.

: Beginning with SBML Level 2 Version 2, objects derived from SBase have an optional attribute named "sboTerm" for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form "SBO:NNNNNNN", where "NNNNNNN" is a seven digit integer number; libSBML simplifies the representation by only storing the "NNNNNNN" integer portion. Thus, in libSBML, the "sboTerm" attribute on SBase has data type int, and SBO identifiers are stored simply as integers.

: SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for "sboTerm". More details can be found in SBML specifications for Level 2 Version 2 and above.

Returns: the value of the "sboTerm" attribute as an integer, or -1 if the value is not set.

Examples:: printSBML.cpp.

int Model::getTypeCode ( ) const

virtual

Returns the libSBML type code for this SBML object.

: LibSBML attaches an identifying code to every kind of SBML object. These are integer constants known as SBML type codes. The names of all the codes begin with the characters SBML_. The set of possible type codes for core elements is defined in the enumeration SBMLTypeCode_t, and in addition, libSBML plug-ins for SBML Level 3 packages define their own extra enumerations of type codes (e.g., SBMLLayoutTypeCode_t for the Level 3 Layout package). Note that different Level 3 package plug-ins may use overlapping type codes; to identify the package to which a given object belongs, call the SBase::getPackageName() method on the object.

The exception to this is lists: all SBML-style list elements have the type SBML_LIST_OF, regardless of what package they are from.

Returns: the SBML type code for this object: SBML_MODEL (default).

Warning: The specific integer values of the possible type codes may be reused by different libSBML plug-ins for SBML Level 3. packages, To fully identify the correct code, it is necessary to invoke both getPackageName() and getTypeCode() (or ListOf::getItemTypeCode()).

See also: getElementName(); getPackageName()

bool Model::isPopulatedAllElementIdList ( ) const

Predicate returning true if libSBML has a list of the ids of all components of this model.

Returns: true if the id list has already been populated, false otherwise.

bool Model::isPopulatedAllElementMetaIdList ( ) const

Predicate returning true if libSBML has a list of the metaids of all components of this model.

Returns: true if the metaid list has already been populated, false otherwise.

bool Model::isPopulatedListFormulaUnitsData ( )

Predicate returning true if libSBML has derived units for the components of this model.

LibSBML can infer the units of measurement associated with different elements of a model. When libSBML does that, it builds a complex internal structure during a resource-intensive operation. This is done automatically only when callers invoke validation (via SBMLDocument::checkConsistency()) and have not turned off the unit validation option.

Callers can force units to be recalculated by calling populateListFormulaUnitsData(). To avoid calling that method unnecessarily, calling programs may first want to invoke this method (isPopulatedListFormulaUnitsData()) to determine whether it is even necessary.

Returns: true if the units have already been computed, false otherwise.

bool SBase::isSetAnnotation ( ) const

inherited

Predicate returning true if this object's "annotation" subelement exists and has content.

Whereas the SBase "notes" subelement is a container for content to be shown directly to humans, the "annotation" element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for "annotation". The element's content type is XML type "any", allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Returns: true if a "annotation" subelement exists, false otherwise.

See also: getAnnotation(); getAnnotationString(); setAnnotation(const XMLNode* annotation); setAnnotation(const std::string& annotation); appendAnnotation(const XMLNode* annotation); appendAnnotation(const std::string& annotation); unsetAnnotation()

Examples:: printAnnotation.cpp.

bool Model::isSetAreaUnits ( ) const

Predicate returning true if this Model's "areaUnits" attribute is set.

Returns: true if the "areaUnits" attribute of this Model is set, false otherwise.

bool Model::isSetConversionFactor ( ) const

Predicate returning true if this Model's "conversionFactor" attribute is set.

Returns: true if the "conversionFactor" attribute of this Model is set, false otherwise.

Note: The "conversionFactor" attribute is available in SBML Level 3 but is not present on Model in lower Levels of SBML.

bool Model::isSetExtentUnits ( ) const

Predicate returning true if this Model's "extentUnits" attribute is set.

Returns: true if the "extentUnits" attribute of this Model is set, false otherwise.

Note: The "extentUnits" attribute is available in SBML Level 3 but is not present on Model in lower Levels of SBML.

bool Model::isSetId ( ) const

virtual

Predicate returning true if this Model's "id" attribute is set.

The identifier given by an object's "id" attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of "id" is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:

     letter ::= 'a'..'z','A'..'Z'
     digit  ::= '0'..'9'
     idChar ::= letter | digit | '_'
     SId    ::= ( letter | '_' ) idChar*

The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined "id" and "name" attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have "id" or "name" attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: "variable" (for the rules and event assignments), "symbol" (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.

With the addition of "id" and "name" attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original "id" methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual "id" attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an "id" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write "id" attributes for those objects.

Returns: true if the "id" attribute of this SBML object is set, false otherwise.

Note: Because of the inconsistent behavior of this function with respect to assignments and rules, it is recommended that callers use isSetIdAttribute() instead.

bool SBase::isSetIdAttribute ( ) const

inherited

Predicate returning true if this object's "id" attribute is set.

The identifier given by an object's "id" attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of "id" is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:

     letter ::= 'a'..'z','A'..'Z'
     digit  ::= '0'..'9'
     idChar ::= letter | digit | '_'
     SId    ::= ( letter | '_' ) idChar*

The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

bool Model::isSetLengthUnits ( ) const

Predicate returning true if this Model's "lengthUnits" attribute is set.

Returns: true if the "lengthUnits" attribute of this Model is set, false otherwise.

Note: The "lengthUnits" attribute is available in SBML Level 3 but is not present on Model in lower Levels of SBML.

bool SBase::isSetMetaId ( ) const

inherited

Predicate returning true if this object's "metaid" attribute is set.

: The optional attribute named "metaid", present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each "metaid" value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the "metaid" attribute used by SBML—something to be aware of if your application-specific XML content inside the "annotation" subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the "metaid" attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the "annotation" subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

Returns: true if the "metaid" attribute of this SBML object is set, false otherwise.

See also: getMetaId(); setMetaId(const std::string& metaid)

Examples:: addingEvidenceCodes_1.cpp, and addingEvidenceCodes_2.cpp.

bool SBase::isSetModelHistory ( )

inherited

Predicate returning true if this object has a ModelHistory object attached to it.

Returns: true if the ModelHistory of this object is set, false otherwise.

Note: In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.

bool Model::isSetName ( ) const

virtual

Predicate returning true if this Model's "name" attribute is set.

: In SBML Level 3 Version 2, the "id" and "name" attributes were moved to SBase directly, instead of being defined individually for many (but not all) objects. LibSBML has for a long time provided functions defined on SBase itself to get, set, and unset those attributes, which would fail or otherwise return empty strings if executed on any object for which those attributes were not defined. Now that all SBase objects define those attributes, those functions now succeed for any object with the appropriate level and version.

The "name" attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of "name" is the type string defined in XML Schema. SBML imposes no restrictions as to the content of "name" attributes beyond those restrictions defined by the string type in XML Schema.

The recommended practice for handling "name" is as follows. If a software tool has the capability for displaying the content of "name" attributes, it should display this content to the user as a component's label instead of the component's "id". If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the "name" attribute is missing on a given component, then the user interface should display the value of the "id" attribute instead. (Script language interpreters are especially likely to display "id" instead of "name".)

As a consequence of the above, authors of systems that automatically generate the values of "id" attributes should be aware some systems may display the "id"'s to the user. Authors therefore may wish to take some care to have their software create "id" values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the "id" attribute be an abbreviated form of the name attribute value.

An additional point worth mentioning is although there are restrictions on the uniqueness of "id" values, there are no restrictions on the uniqueness of "name" values in a model. This allows software applications leeway in assigning component identifiers.

Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a "name" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write "name" attributes for those objects.

Returns: true if the "name" attribute of this SBML object is set, false otherwise.

See also: getName(); setName(const std::string& sid); unsetName()

Reimplemented from SBase.

bool SBase::isSetNotes ( ) const

inherited

Predicate returning true if this object's "notes" subelement exists and has content.

The optional SBML element named "notes", present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.

The format of "notes" elements must be XHTML 1.0. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

Returns: true if a "notes" subelement exists, false otherwise.

See also: getNotes(); getNotesString(); setNotes(const XMLNode* notes); setNotes(const std::string& notes, bool addXHTMLMarkup); appendNotes(const XMLNode* notes); appendNotes(const std::string& notes); unsetNotes(); SyntaxChecker::hasExpectedXHTMLSyntax()

: The user data associated with an SBML object can be used by an application developer to attach custom information to that object in the model. In case of a deep copy, this attribute will passed as it is. The attribute will never be interpreted by libSBML.

: The user data associated with an SBML object can be used by an application developer to attach custom information to that object in the model. In case of a deep copy, this data will passed as-is. The data attribute will never be interpreted by libSBML.

Returns: boolean, true if this object's user data has been set, false otherwise.

bool Model::isSetVolumeUnits ( ) const

Predicate returning true if this Model's "volumeUnits" attribute is set.

Returns: true if the "volumeUnits" attribute of this Model is set, false otherwise.

Note: The "volumeUnits" attribute is available in SBML Level 3 but is not present on Model in lower Levels of SBML.

bool SBase::matchesRequiredSBMLNamespacesForAddition ( const SBase * sb )

inherited

Returns true if this object's set of XML namespaces are a subset of the given object's XML namespaces.

: The SBMLNamespaces object encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and (in Level 3) packages used in addition to SBML Level 3 Core. A common approach to using libSBML's SBMLNamespaces facilities is to create an SBMLNamespaces object somewhere in a program once, then hand that object as needed to object constructors that accept SBMLNamespaces as arguments.

Parameters

sb	an object to compare with respect to namespaces.

Returns: boolean, true if this object's collection of namespaces is a subset of sb's, false otherwise.

void Model::populateAllElementIdList ( )

Populates the internal list of the identifiers of all elements within this Model object.

This method tells libSBML to retrieve the identifiers of all elements of the enclosing Model object. The result is stored in an internal list of ids. Users can access the resulting data by calling the method getAllElementIdList().

Warning: Retrieving all elements within a model is a time-consuming operation. Callers may want to call isPopulatedAllElementIdList() to determine whether the id list may already have been populated.

See also: isPopulatedAllElementIdList()

void Model::populateAllElementMetaIdList ( )

Populates the internal list of the metaids of all elements within this Model object.

This method tells libSBML to retrieve the identifiers of all elements of the enclosing Model object. The result is stored in an internal list of metaids. Users can access the resulting data by calling the method getAllElementMetaIdList().

Warning: Retrieving all elements within a model is a time-consuming operation. Callers may want to call isPopulatedAllElementMetaIdList() to determine whether the metaid list may already have been populated.

See also: isPopulatedAllElementMetaIdList()

void Model::populateListFormulaUnitsData ( )

Populates the internal list of derived units for this Model object.

This method tells libSBML to (re)calculate all units for all components of the enclosing Model object. The result is stored in an internal list of unit data. Users can access the resulting data by calling the method SBase::getDerivedUnitDefinition() available on most objects. (The name "formula units data" is drawn from the name of the internal objects libSBML uses to store the data; note that these internal objects are not exposed to callers, because callers can interact with the results using the ordinary SBML unit objects.)

This method is used by libSBML itself in the validator concerned with unit consistency. The unit consistency validator (like all other validators in libSBML) is invoked by using SBMLDocument::checkConsistency(), with the consistency checks for the category LIBSBML_CAT_UNITS_CONSISTENCY turned on. The method populateListFormulaUnitsData() does not need to be called prior to invoking the validator if unit consistency checking has not been turned off. This method is only provided for cases when callers have a special need to force the unit data to be recalculated. For instance, during construction of a model, a caller may want to interrogate libSBML's inferred units without invoking full-blown model validation; this is a scenario in which calling populateListFormulaUnitsData() may be useful.

Warning: Computing and inferring units is a time-consuming operation. Callers may want to call isPopulatedListFormulaUnitsData() to determine whether the units may already have been computed, to save themselves the need of invoking unit inference unnecessarily.

int SBase::removeTopLevelAnnotationElement	(	const std::string &	elementName,
		const std::string	elementURI = `""`,
		bool	removeEmpty = `true`
	)

inherited

Removes the top-level element within the "annotation" subelement of this SBML object with the given name and optional URI.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Calling this method allows a particular annotation element to be removed whilst the remaining annotations remain intact.

Parameters

elementName	a string representing the name of the top level annotation element that is to be removed.
elementURI	an optional string that is used to check both the name and URI of the top level element to be removed.
removeEmpty	if after removing of the element, the annotation is empty, and the removeEmpty argument is true, the annotation node will be deleted (default).

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

void SBase::renameMetaIdRefs	(	const std::string &	oldid,
		const std::string &	newid
	)

virtualinherited

Replaces all uses of a given meta identifier attribute value with another value.

: In SBML, object "meta" identifiers are of the XML data type ID; the SBML object attribute itself is typically named metaid. All attributes that hold values referring to values of type ID are of the XML data type IDREF. They are also sometimes informally referred to as "metaid refs", in analogy to the SBML-defined type SIdRef.

This method works by looking at all meta-identifier attribute values, comparing the identifiers to the value of oldid. If any matches are found, the matching identifiers are replaced with newid. The method does not descend into child elements.

Parameters

oldid	the old identifier.
newid	the new identifier.

Reimplemented in Port, and GraphicalObject.

void Model::renameSIdRefs	(	const std::string &	oldid,
		const std::string &	newid
	)

virtual

Replaces all uses of a given SIdRef type attribute value with another value.

In SBML, object identifiers are of a data type called SId. In SBML Level 3, an explicit data type called SIdRef was introduced for attribute values that refer to SId values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as "referring to an identifier", but the effective data type was the same as SIdRef in Level 3. These and other methods of libSBML refer to the type SIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.

This method works by looking at all attributes and (if appropriate) mathematical formulas in MathML content, comparing the referenced identifiers to the value of oldid. If any matches are found, the matching values are replaced with newid. The method does not descend into child elements.

Parameters

oldid	the old identifier.

void Model::renameUnitSIdRefs	(	const std::string &	oldid,
		const std::string &	newid
	)

virtual

Replaces all uses of a given UnitSIdRef type attribute value with another value.

: In SBML, unit definitions have identifiers of type UnitSId. In SBML Level 3, an explicit data type called UnitSIdRef was introduced for attribute values that refer to UnitSId values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as "referring to a unit identifier", but the effective data type was the same as UnitSIdRef in Level 3. These and other methods of libSBML refer to the type UnitSIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.

This method works by looking at all unit identifier attribute values (including, if appropriate, inside mathematical formulas), comparing the referenced unit identifiers to the value of oldid. If any matches are found, the matching values are replaced with newid. The method does not descend into child elements.

Parameters

oldid	the old identifier.
newid	the new identifier.

int SBase::replaceTopLevelAnnotationElement ( const XMLNode * annotation )

inherited

Replaces the given top-level element within the "annotation" subelement of this SBML object and with the annotation element supplied.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

This method determines the name of the element to be replaced from the annotation argument. Functionally it is equivalent to calling removeTopLevelAnnotationElement(name) followed by calling appendAnnotation(annotation_with_name), with the exception that the placement of the annotation element remains the same.

Parameters

annotation XMLNode representing the replacement top level annotation.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

See also: removeTopLevelAnnotationElement(const std::string elementName, const std::string elementURI, bool removeEmpty); replaceTopLevelAnnotationElement(const std::string&)

int Model::setAnnotation ( const XMLNode * annotation )

virtual

Sets the value of the "annotation" subelement of this SBML object to a copy of annotation.

Any existing content of the "annotation" subelement is discarded. Unless you have taken steps to first copy and reconstitute any existing annotations into the annotation that is about to be assigned, it is likely that performing such wholesale replacement is unfriendly towards other software applications whose annotations are discarded. An alternative may be to use appendAnnotation().

Parameters

annotation an XML structure that is to be used as the content of the "annotation" subelement of this object.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:

LIBSBML_OPERATION_SUCCESS

int Model::setId ( const std::string & sid )

virtual

Sets the value of the "id" attribute of this Model.

: The string sid is copied.

The identifier given by an object's "id" attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of "id" is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:

     letter ::= 'a'..'z','A'..'Z'
     digit  ::= '0'..'9'
     idChar ::= letter | digit | '_'
     SId    ::= ( letter | '_' ) idChar*

The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined "id" and "name" attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have "id" or "name" attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: "variable" (for the rules and event assignments), "symbol" (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.

With the addition of "id" and "name" attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original "id" methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual "id" attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an "id" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write "id" attributes for those objects.

Parameters

sid	the string to use as the identifier of this object.

Parameters

units the new lengthUnits for the Model.

Returns

int SBase::setMetaId ( const std::string & metaid )

inherited

Sets the value of the meta-identifier attribute of this SBML object.

: The optional attribute named "metaid", present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each "metaid" value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the "metaid" attribute used by SBML—something to be aware of if your application-specific XML content inside the "annotation" subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the "metaid" attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the "annotation" subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

The string metaid is copied.

Parameters

metaid the identifier string to use as the value of the "metaid" attribute.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

The content of xmlns is copied, and this object's existing namespace content is deleted.

The SBMLNamespaces object encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and (in Level 3) packages used in addition to SBML Level 3 Core.

Parameters

int SBase::setNotes ( const XMLNode * notes )

inherited

Sets the value of the "notes" subelement of this SBML object.

The content of notes is copied, and any existing content of this object's "notes" subelement is deleted.

The optional SBML element named "notes", present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.

The format of "notes" elements must be XHTML 1.0. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

Parameters

notes an XML structure that is to be used as the content of the "notes" subelement of this object.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

The following code illustrates a very simple way of setting the notes using this method. Here, the object being annotated is the whole SBML document, but that is for illustration purposes only; you could of course use this same approach to annotate any other SBML component.

SBMLDocument* s = new SBMLDocument(3, 1);

s->setNotes("<body xmlns='http://www.w3.org/1999/xhtml'><p>here is my note</p></body>");

Parameters

notes	an XML string that is to be used as the content of the "notes" subelement of this object.
addXHTMLMarkup	a boolean indicating whether to wrap the contents of the `notes` argument with XHTML paragraph (`<p>`) tags. This is appropriate when the string in `notes` does not already containg the appropriate XHTML markup.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

int SBase::setSBOTerm ( int value )

virtualinherited

Sets the value of the "sboTerm" attribute.

: Beginning with SBML Level 2 Version 2, objects derived from SBase have an optional attribute named "sboTerm" for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form "SBO:NNNNNNN", where "NNNNNNN" is a seven digit integer number; libSBML simplifies the representation by only storing the "NNNNNNN" integer portion. Thus, in libSBML, the "sboTerm" attribute on SBase has data type int, and SBO identifiers are stored simply as integers.

: SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for "sboTerm". More details can be found in SBML specifications for Level 2 Version 2 and above.

Parameters

value the NNNNNNN integer portion of the SBO identifier.

Returns

char * SBase::toSBML ( )

inherited

Returns a string consisting of a partial SBML corresponding to just this object.

Returns: the partial SBML that describes this SBML object.

Warning: This is primarily provided for testing and debugging purposes. It may be removed in a future version of libSBML.

XMLNode* SBase::toXMLNode ( )

inherited

Returns this element as an XMLNode.

Returns: this element as an XMLNode.

Warning: This operation is computationally expensive, because the element has to be fully serialized to a string and then parsed into the XMLNode structure. Attempting to convert a large tree structure (e.g., a large Model) may consume significant computer memory and time.

int SBase::unsetAnnotation ( )

inherited

Unsets the value of the "annotation" subelement of this SBML object.

Whereas the SBase "notes" subelement is a container for content to be shown directly to humans, the "annotation" element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for "annotation". The element's content type is XML type "any", allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:

Note: The "extentUnits" attribute is available in SBML Level 3 but is not present on Model in lower Levels of SBML.

int Model::unsetId ( )

virtual

Unsets the value of the "id" attribute of this Model.

The identifier given by an object's "id" attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of "id" is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:

     letter ::= 'a'..'z','A'..'Z'
     digit  ::= '0'..'9'
     idChar ::= letter | digit | '_'
     SId    ::= ( letter | '_' ) idChar*

The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined "id" and "name" attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have "id" or "name" attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: "variable" (for the rules and event assignments), "symbol" (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.

With the addition of "id" and "name" attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original "id" methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual "id" attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an "id" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write "id" attributes for those objects.

Reimplemented from SBase.

int SBase::unsetIdAttribute ( )

inherited

Unsets the value of the "id" attribute of this SBML object.

Most (but not all) objects in SBML include two common attributes: "id" and "name". The identifier given by an object's "id" attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

See also: getIdAttribute(); setIdAttribute(const std::string& sid); isSetIdAttribute()

int Model::unsetLengthUnits ( )

Unsets the value of the "lengthUnits" attribute of this Model.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

Note: The "lengthUnits" attribute is available in SBML Level 3 but is not present on Model in lower Levels of SBML.

int SBase::unsetMetaId ( )

inherited

Unsets the value of the "metaid" attribute of this SBML object.

: The optional attribute named "metaid", present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each "metaid" value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the "metaid" attribute used by SBML—something to be aware of if your application-specific XML content inside the "annotation" subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the "metaid" attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the "annotation" subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

int SBase::unsetModelHistory ( )

inherited

Unsets the ModelHistory object attached to this object.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

Note: In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.

int Model::unsetName ( )

virtual

Unsets the value of the "name" attribute of this Model.

: In SBML Level 3 Version 2, the "id" and "name" attributes were moved to SBase directly, instead of being defined individually for many (but not all) objects. LibSBML has for a long time provided functions defined on SBase itself to get, set, and unset those attributes, which would fail or otherwise return empty strings if executed on any object for which those attributes were not defined. Now that all SBase objects define those attributes, those functions now succeed for any object with the appropriate level and version.

The "name" attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of "name" is the type string defined in XML Schema. SBML imposes no restrictions as to the content of "name" attributes beyond those restrictions defined by the string type in XML Schema.

The recommended practice for handling "name" is as follows. If a software tool has the capability for displaying the content of "name" attributes, it should display this content to the user as a component's label instead of the component's "id". If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the "name" attribute is missing on a given component, then the user interface should display the value of the "id" attribute instead. (Script language interpreters are especially likely to display "id" instead of "name".)

As a consequence of the above, authors of systems that automatically generate the values of "id" attributes should be aware some systems may display the "id"'s to the user. Authors therefore may wish to take some care to have their software create "id" values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the "id" attribute be an abbreviated form of the name attribute value.

An additional point worth mentioning is although there are restrictions on the uniqueness of "id" values, there are no restrictions on the uniqueness of "name" values in a model. This allows software applications leeway in assigning component identifiers.

Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a "name" attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write "name" attributes for those objects.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. The possible values returned by this function are:

See also: getName(); setName(const std::string& sid); isSetName()

Reimplemented from SBase.

int SBase::unsetNotes ( )

inherited

Unsets the value of the "notes" subelement of this SBML object.

The optional SBML element named "notes", present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the "notes" element would be to contain formatted user comments about the model element in which the "notes" element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for "notes", allowing users considerable freedom when adding comments to their models.

The format of "notes" elements must be XHTML 1.0. To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how "notes" element content must be structured.

Returns

integer value indicating success/failure of the function. The value is drawn from the enumeration OperationReturnValues_t. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:

LIBSBML_OPERATION_SUCCESS

See also: getNotesString(); isSetNotes(); setNotes(const XMLNode* notes); setNotes(const std::string& notes, bool addXHTMLMarkup); appendNotes(const XMLNode* notes); appendNotes(const std::string& notes); SyntaxChecker::hasExpectedXHTMLSyntax()

Examples:: unsetNotes.cpp.

int SBase::unsetUserData ( )

inherited

Unsets the user data of this element.

: The user data associated with an SBML object can be used by an application developer to attach custom information to that object in the model. In case of a deep copy, this attribute will passed as it is. The attribute will never be interpreted by libSBML.
