Detailed Description

render Representation of a linear gradient.

The concept of a linear gradient is more or or less taken from SVG. A linear gradient is defined by a vector which determines the direction and the length of the gradient. So for a valid gradient, this vector should have a length different from 0. Otherwise, all restrictions for the GradientBase class apply.

The vector for a linear gradient is defined by a start and an endpoint and each point consists of three absolute-relative value pairs.

For examples of LinearGradient objects, see the SBML Render package specification and/or the SVG specification.

Constructor & Destructor Documentation

LinearGradient::LinearGradient ( unsigned int  level = RenderExtension::getDefaultLevel(),
unsigned int  version = RenderExtension::getDefaultVersion(),
unsigned int  pkgVersion = RenderExtension::getDefaultPackageVersion() 
)

Creates a new LinearGradient using the given SBML Level, Version and “render” package version.

Parameters
levelan unsigned int, the SBML Level to assign to this LinearGradient.
versionan unsigned int, the SBML Version to assign to this LinearGradient.
pkgVersionan unsigned int, the SBML Render Version to assign to this LinearGradient.
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. For packages, this means that the parent object to which this package element is being added must have been created with the package namespace, or that the package namespace was added to it, even if that parent is not a package object itself.
LinearGradient::LinearGradient ( RenderPkgNamespaces renderns)

Creates a new LinearGradient using the given RenderPkgNamespaces object.

The package namespaces object used in this constructor is derived from a SBMLNamespaces object, which encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and package version and name information used in addition to SBML Level 3 Core. A common approach to using libSBML's SBMLNamespaces facilities is to create an package namespace object somewhere in a program once, then hand that object as needed to object constructors of that package that accept it as and argument, such as this one.
Parameters
rendernsthe RenderPkgNamespaces object.

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.

LinearGradient::LinearGradient ( const XMLNode node,
unsigned int  l2version = 4 
)

Creates a new LinearGradient object from the given XMLNode object.

The XMLNode object has to contain a valid XML representation of a LinearGradient object as defined in the render extension specification. This method is normally called when render information is read from a file and should normally not have to be called explicitly.

Parameters
nodethe XMLNode object reference that describes the LinearGradient object to be instantiated.
l2versionan integer indicating the version of SBML Level 2
LinearGradient::LinearGradient ( RenderPkgNamespaces renderns,
const std::string &  id 
)

Constructor which creates a LinearGradient with no gradient stops.

The id is set to the given value. The LinearGradient object is invalid until it has an id and at least two gradient stops. The start and the end of the linear gradient vector are set to (0,0,0). A linear gradient with a vector of length zero should also be considered invalid.

Parameters
rendernsthe SBMLNamespaces object for the SBML "render" package
idthe new id for the LinearGradient.
Warning
This constructor is deprecated. The new libSBML API uses constructors that either take the SBML Level and Version, or take an SBMLNamespaces object.
LinearGradient::LinearGradient ( const LinearGradient orig)

Copy constructor for LinearGradient.

Parameters
origthe LinearGradient instance to copy.
LinearGradient::~LinearGradient ( )
virtual

Destructor for LinearGradient.

Member Function Documentation

virtual bool LinearGradient::accept ( SBMLVisitor v) const
virtual

Accepts the given SBMLVisitor for this instance of LinearGradient.

Parameters
vthe SBMLVisitor instance to be used.
Returns
the result of calling v.visit().
int SBase::addCVTerm ( CVTerm term,
bool  newBag = false 
)
inherited

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

Parameters
termthe CVTerm to assign.
newBagif 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:
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. 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.
Examples:
addCVTerms.cpp, addingEvidenceCodes_1.cpp, and addingEvidenceCodes_2.cpp.
int GradientBase::addGradientStop ( const GradientStop gs)

int SBase::appendAnnotation ( const XMLNode annotation)
virtualinherited

Appends the given annotation to the "annotation" subelement of this 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.

Unlike SBase::setAnnotation(const XMLNode* annotation) or SBase::setAnnotation(const std::string& annotation), this method allows other annotations to be preserved when an application adds its own data.

Parameters
annotationan XML structure that is to be copied and appended to 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. The possible values returned by this function are:

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

void SBase::deleteDisabledPlugins ( bool  recursive = true)
inherited

Deletes all information stored in disabled plugins.

If the plugin is re-enabled later, it will then not have any previously-stored information.

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
recursiveif 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
pkgURIthe URI of the package.
pkgPrefixthe 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:

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

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.

This method walks down the list of all SBML Level 3 packages used by this object and returns all child objects defined by those packages.

Parameters
filtera 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 pointer to a List of pointers to all children objects from plug-ins.
SBase * SBase::getAncestorOfType ( int  type,
const std::string &  pkgName = "core" 
)
inherited

Returns the first ancestor object that has the given SBML type code from the given package.

LibSBML attaches an identifying code to every kind of SBML object. These are known as SBML type codes. The set of possible type codes is defined in the enumeration SBMLTypeCode_t. The names of the type codes all begin with the characters SBML_.

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
typethe 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.
const SBase * SBase::getAncestorOfType ( int  type,

XMLNode * SBase::getAnnotation ( )
inherited

Returns the content of the "annotation" subelement of this 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.)

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
metaidstring representing the "metaid" attribute value of the object to find.
Returns
pointer to the first element found with the given meta-identifier.
SBase * GradientBase::getElementByMetaId ( const std::string &  metaid)
virtualinherited

const std::string & GradientBase::getId ( ) const
virtualinherited

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

Returns
the value of the "id" attribute of this GradientBase as a string.

Reimplemented from SBase.

const string & SBase::getIdAttribute ( ) const
inherited

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

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 SBML object, if set and valid for this level and version of SBML; an empty string otherwise.
Note
Because of the inconsistent behavior of this function with respect to assignments and rules, callers should use getIdAttribute() instead.

unsigned int SBase::getLevel ( ) const
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.)
Returns
the SBML level of this SBML object.

unsigned int SBase::getLine ( ) const
inherited

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

Returns
the line 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 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

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().

unsigned int SBase::getNumDisabledPlugins ( ) const
inherited

Returns the number of disabled plug-in objects (extension interfaces) for SBML Level 3 package extensions known.

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.

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
resourcestring 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
resourcestring 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.

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:

int LinearGradient::getTypeCode ( ) const
virtual

Returns the libSBML type code for this LinearGradient 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_RENDER_LINEARGRADIENT.
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()).

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.

Reimplemented from SBase.

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.

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.

setIdAttribute(const std::string& sid)

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.

bool GradientBase::isSetName ( ) const

Returns
true if this GradientBase's "name" attribute has been set, otherwise false is returned.

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.

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
sban 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.
bool SBase::matchesRequiredSBMLNamespacesForAddition ( const SBase sb) const

LinearGradient & LinearGradient::operator= ( const LinearGradient rhs)

Assignment operator for LinearGradient.

Parameters
rhsthe LinearGradient object whose values are to be used as the basis of the assignment.
void SBase::read ( XMLNode node,
XMLErrorSeverityOverride_t  flag = LIBSBML_OVERRIDE_DISABLED 
)
inherited

Reads (initializes) this SBML object by reading from the given XMLNode.

Parameters
nodethe XMLNode to read from.
flagan optional flag that determines how how errors are logged during the reading process.
Warning
This method is computationally expensive, because the given node has to be serialized to a string first. Attempting to serialize a large tree structure (e.g., a large Model) may consume significant computer memory and time.
int SBase::removeFromParentAndDelete ( )
virtualinherited

Removes this object from its parent.

If the parent was storing this object as a pointer, it is deleted. If not, it is simply cleared (as in ListOf objects). This is a pure virtual method, as every SBase element has different parents, and therefore different methods of removing itself. Will fail (and not delete itself) if it has no parent object. This function is designed to be overridden, but for all objects whose parent is of the class ListOf, the default implementation will work.

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:

Reimplemented in Model, KineticLaw, SBaseRef, StoichiometryMath, Trigger, Delay, ListOf, Priority, ModelDefinition, and ReplacedBy.

GradientStop* GradientBase::removeGradientStop ( unsigned int  n)
inherited

Removes the nth GradientStop from this GradientBase and returns a pointer to it.

Parameters
nan unsigned int representing the index of the GradientStop to remove.
Returns
a pointer to the nth GradientStop in this GradientBase.
Warning
The pointer that is returned by this function is owned by the caller, who is responsible for deleting it. Any changes made to the element will not be reflected in any resulting SBML document unless the element is added to an SBML Document. Even in this case, the element's deletion is still the responsibility of the caller with two exceptions: if it is used as the "disownedItem" in the ListOf::appendAndOwn() or ListOf::insertAndOwn() functions. All other functions in libsbml add a copy of the element, and do not transfer ownership of the pointer.

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
elementNamea string representing the name of the top level annotation element that is to be removed.
elementURIan optional string that is used to check both the name and URI of the top level element to be removed.
removeEmptyif 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
oldidthe old identifier.
newidthe new identifier.

Reimplemented in Port, and GraphicalObject.

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

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
oldidthe old identifier.
newidthe new identifier.

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

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
oldidthe old identifier.
newidthe 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
annotationXMLNode 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:

int SBase::setAnnotation ( const XMLNode annotation)
virtualinherited

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

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

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.

Call this method will result in any existing content of the "annotation" subelement to be 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 SBase::appendAnnotation(const XMLNode* annotation) or SBase::appendAnnotation(const std::string& annotation).

Parameters
annotationan XML structure that is to be used as the new 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:

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

Parameters
idthe string value of the "id" attribute to be set.
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: Calling this function with id = NULL or an empty string is equivalent to calling unsetId().

Reimplemented from SBase.

int SBase::setIdAttribute ( const std::string &  sid)
virtualinherited

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

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
sidthe string to use as the identifier 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:

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
metaidthe 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 history is copied, and this object's existing model history content is deleted.

Parameters
historyModelHistory 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:
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 GradientBase::setName ( const std::string &  name)
virtualinherited

Sets the value of the "name" attribute of this GradientBase.

Parameters
namethe string value of the "name" attribute to be set.
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: Calling this function with name = NULL or an empty string is equivalent to calling unsetName().

Reimplemented from SBase.

int SBase::setNamespaces ( XMLNamespaces xmlns)
inherited

Sets the namespaces relevant of this SBML object.

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
xmlnsthe namespaces to set.
Returns

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

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
notesan XML string that is to be used as the content of the "notes" subelement of this object.
addXHTMLMarkupa 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.

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
valuethe NNNNNNN integer portion of the SBO 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:

int SBase::setSBOTerm ( const std::string &  sboid)
virtualinherited

Sets the value of the "sboTerm" attribute by string.

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
sboidthe SBO identifier string of the form "SBO:NNNNNNN".

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.
virtual XMLNode LinearGradient::toXML ( ) const
virtual

Creates an XMLNode object from this LinearGradient object.

Returns
the XMLNode with the XML representation for the LinearGradient object.

Implements GradientBase.

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:

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:

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.
virtual int GradientBase::unsetName ( )
virtualinherited

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

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:

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:

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:
The attribute "spreadMethod" on a GradientBase object is used by GradientBase elements to decide how gradients propagate over the whole element they are applied to. The following are the allowable values for "spreadMethod":
  • "pad", the gradient color at the endpoint of the vector defines how the gradient is continued beyond that point (default value).
