Detailed Description

multi A subclass of Reaction for changes of an internal species bond.

An IntraSpeciesReaction is derived from Reaction for the reactions happening within a Species. A particular Reaction may happen within a Species as an IntraSpeciesReaction if the following conditions are fulfilled:

  • The Reaction is either an association reaction or a dissociation reaction.

Note: Technically, transformations are also reactions happening with one Species, but they do not have the ambiguity of association and dissociation reactions. Therefore, a transformation reaction does not have to be defined as an IntraSpeciesReaction.

Constructor & Destructor Documentation

def libsbml.IntraSpeciesReaction.__init__ (   self,
  args 
)

This method has multiple variants; they differ in the arguments they accept.

__init__(long  level, long  version, long  pkgVersion)   IntraSpeciesReaction
__init__(long  level, long  version)   IntraSpeciesReaction
__init__(long  level)   IntraSpeciesReaction
__init__()   IntraSpeciesReaction
__init__(MultiPkgNamespaces multins)   IntraSpeciesReaction
__init__(IntraSpeciesReaction orig)   IntraSpeciesReaction

Each variant is described separately below.


Method variant with the following signature:
IntraSpeciesReaction(IntraSpeciesReaction orig)

Copy constructor for IntraSpeciesReaction.

Parameters
origthe IntraSpeciesReaction instance to copy.

Method variant with the following signature:
IntraSpeciesReaction(long level = MultiExtension.getDefaultLevel(), long version = MultiExtension.getDefaultVersion(), long pkgVersion = MultiExtension.getDefaultPackageVersion())

Creates a new IntraSpeciesReaction with the given level, version, and package version.

Parameters
levelthe SBML Level.
versionthe Version within the SBML Level.
pkgVersionthe version of the package.
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.
Owing to the way that language interfaces are created in libSBML, this documentation may show methods that define default values for parameters with text that has the form parameter = value. This is not to be intepreted as a Python keyword argument; the use of a parameter name followed by an equals sign followed by a value is only meant to indicate a default value if the argument is not provided at all. It is not a keyword in the Python sense.

Method variant with the following signature:
IntraSpeciesReaction(MultiPkgNamespaces multins)

Creates a new IntraSpeciesReaction with the given MultiPkgNamespaces 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
multinsthe MultiPkgNamespaces 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. 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.

def libsbml.SBase.addCVTerm (   self,
  term,
  newBag = False 
)
inherited

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

addCVTerm(CVTerm term, bool newBag)   int
addCVTerm(CVTerm term)   int
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 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.
Owing to the way that language interfaces are created in libSBML, this documentation may show methods that define default values for parameters with text that has the form parameter = value.

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.

def libsbml.SBase.appendAnnotation (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

appendAnnotation(XMLNode annotation)   int
appendAnnotation(string annotation)   int

Each variant is described separately below.


Method variant with the following signature:
appendAnnotation(XMLNode annotation)

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() or SBase.setAnnotation(), 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 possible values returned by this function are:

def libsbml.SBase.appendNotes (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

appendNotes(XMLNode notes)   int
appendNotes(string notes)   int

Each variant is described separately below.


Method variant with the following signature:
appendNotes(string notes)

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

The content of the parameter 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 string that is to appended to the content of the 'notes' subelement of this object.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

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.

getNumDisabledPlugins()
def libsbml.SBase.disablePackage (   self,
  pkgURI,
  pkgPrefix 
)
inherited

Disables the given SBML Level 3 package on this object.

disablePackage(string pkgURI, string pkgPrefix)   int

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:

1 import sys
2 import os.path
3 from libsbml import *
4 
5 # We read an SBML L3V1 model that uses the 'comp' package.
6 
7 doc = readSBML('sbml-file-with-comp-elements.xml');
8 if doc.getNumErrors() > 0:
9  print('readSBML encountered errors while reading the file.')
10  doc.printErrors()
11  sys.exit(1)
12 
13 # We extract one of the species from the model.
14 
15 model = doc.getModel()
16 if model == None:
17  print('Unable to retrieve Model object')
18  sys.exit(1)
19 
20 s1 = model.getSpecies(0)
21 if s1 == None:
22  print('Unable to retrieve Species object')
23  sys.exit(1)
24 
25 # We construct a new model.
26 # This model does not use the 'comp' package.
27 
28 try:
29  newDoc = SBMLDocument(3, 1)
30 except ValueError:
31  print('Could not create SBMLDocument object')
32  sys.exit(1)
33 
34 newModel = newDoc.createModel()
35 if newModel == None:
36  print('Unable to create new Model object')
37  sys.exit(1)
38 
39 # The following would normally fail with an error, because
40 # addSpecies() would first check that the parent of the given
41 # object has namespaces declared, and will discover that s1
42 # does but newModel does not.
43 
44 # newModel.addSpecies(s1)
45 
46 # However, if we disable the 'comp' package on s1, then the
47 # call to addSpecies will work.
48 
49 compNS = 'http://www.sbml.org/sbml/level3/version1/comp/version1'
50 status = s1.disablePackage(compNS, 'comp')
51 if status != LIBSBML_OPERATION_SUCCESS:
52  print('Unable to disable package.')
53  sys.exit(1)
54 
55 newSpecies = newModel.addSpecies(s1) # This will work now.
56 if newSpecies == None:
57  print('Could not add Species') # (This will not happen,
58  sys.exit(1) # but always check errors.)

def libsbml.SBase.getAncestorOfType (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

getAncestorOfType(int type, string pkgName)   SBase
getAncestorOfType(int type)   SBase

Each variant is described separately below.


Method variant with the following signature:
getAncestorOfType(int type, string pkgName = 'core')

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. In the Python language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbml. 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 SBML object type code, or None 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 None.
Note
Owing to the way that language interfaces are created in libSBML, this documentation may show methods that define default values for parameters with text that has the form parameter = value. This is not to be intepreted as a Python keyword argument; the use of a parameter name followed by an equals sign followed by a value is only meant to indicate a default value if the argument is not provided at all. It is not a keyword in the Python sense.

def libsbml.SBase.getAnnotation (   self,
  args 
)
inherited

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

getAnnotation()   XMLNode
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.

def libsbml.SBase.getColumn (   self)
inherited

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

getColumn()   long
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.)

def libsbml.Reaction.getFast (   self)
inherited

Returns the value of the 'fast' attribute of this Reaction.

getFast()   bool
In SBML Level 3 Version 2, the 'fast' attribute was removed. All reactions are assumed to be equivalent to reactions in previous levels/versions that have a 'fast' attribute value of False. Users should be aware that even for previous levels/versions of the specification, 'fast' attribute values of True never achieved widespread support, and many software packages may ignore it. To achieve the same or similar effects as setting the fast attribute to True for a given reaction, the KineticLaw attribute should be constructed to produce a value in the desired time scale, or else the reaction could be replaced with an AssignmentRule or AlgebraicRule.
Returns
the 'fast' status of this Reaction.
Warning
SBML definitions before SBML Level 2 Version 2 incorrectly indicated that software tools could ignore the 'fast' attribute if they did not implement support for the corresponding concept; however, further research in SBML has revealed that this is not true, and 'fast' cannot be ignored if it is set to True. Beginning with SBML Level 2 Versions 2, the SBML specifications therefore stipulate that if a model has any reactions with 'fast' set to True, a software tool must be able to respect the attribute or else indicate to the user that it does not have the capacity to do so. Readers are directed to the SBML specifications, which provides more detail about the conditions under which a reaction can be considered to be fast in this sense.
def libsbml.Reaction.getId (   self)
inherited

Returns the value of the 'id' attribute of this Reaction.

getId()   string
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 Reaction.

def libsbml.SBase.getIdAttribute (   self)

getIdAttribute()   string
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'.

def libsbml.SBase.getLevel (   self)
inherited

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

getLevel()   long
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.

def libsbml.SBase.getLine (   self)
inherited

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

getLine()   long
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.)

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.

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.

Returns
a pointer to a List of pointers to all children objects from plug-ins.
def libsbml.Reaction.getListOfModifiers (   self,

def libsbml.SBase.getMetaId (   self)
inherited

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

getMetaId()   string
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.

def libsbml.Reaction.getModifier (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

getModifier(long  n)   ModifierSpeciesReference
getModifier(string species)   ModifierSpeciesReference

Each variant is described separately below.


Method variant with the following signature:
getModifier(string species)

Returns the modifier species (as a ModifierSpeciesReference object) having a specific identifier in this Reaction.

Parameters
speciesthe identifier of the modifier Species ('species' attribute of the ModifierSpeciesReference object).
Returns
a ModifierSpeciesReference object, or None if no species with the given identifier species appears as a modifier in this Reaction.

Method variant with the following signature:
getModifier(long n)

Returns the nth modifier species (as a ModifierSpeciesReference object) in the list of modifiers of this Reaction.

Callers should first call getNumModifiers() to find out how many modifiers there are, to avoid using an invalid index number.

Parameters
nthe index of the modifier species sought.
Returns
the nth modifier (as a ModifierSpeciesReference object) of this Reaction. If the index n is invalid, None is returned.
def libsbml.Reaction.getName (   self)
inherited

Returns the value of the 'name' attribute of this Reaction object.

getName()   string
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.

def libsbml.SBase.getNamespaces (   self)
inherited

Returns a list of the XML Namespaces declared on the SBML document owning this object.

def libsbml.SBase.getNotes (   self,
  args 
)
inherited

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

getNotes()   XMLNode
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.

getNumDisabledPlugins()   long
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.

def libsbml.SBase.getResourceBiologicalQualifier (   self,
  resource 
)
inherited

Returns the MIRIAM biological qualifier associated with the given resource.

getResourceBiologicalQualifier(string resource)   long

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 valueswhose names begin with BQB_ in the interface class libsbml.

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 valuewhose name begins with BQB_ from the interface class libsbml.

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 are up to date with MIRIAM at the time of a given libSBML release. The set of values in list of BQB_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.
def libsbml.SBase.getResourceModelQualifier (   self,
  resource 
)
inherited

Returns the MIRIAM model qualifier associated with the given resource.

getResourceModelQualifier(string resource)   long

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 valueswhose names begin with BQM_ in the interface class libsbml.

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 valuewhose name begins with BQM_ from the interface class libsbml.

Parameters
resourcestring representing the resource; e.g., 'http://www.geneontology.org/#GO:0005892'.
Returns
the model qualifier type associated with the resource, or BQM_UNKNOWN if the resource does not exist.
Note
The set of MIRIAM model qualifiers grows over time, although relatively slowly. The values are up to date with MIRIAM at the time of a given libSBML release. The set of values in list of BQM_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.

getSBMLDocument()   SBMLDocument
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

def libsbml.SBase.getSBOTerm (   self)
inherited

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

getSBOTerm()   int
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.
def libsbml.SBase.getSBOTermAsURL (   self)
inherited

Returns the URL representation of the 'sboTerm' attribute of this object.

getSBOTermAsURL()   string

This method returns the entire SBO identifier as a text string in the form http://identifiers.org/biomodels.sbo/SBO:NNNNNNN'.

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 identifiers.org URL, or an empty string if the value is not set.
def libsbml.SBase.getSBOTermID (   self)
inherited

Returns the string representation of the 'sboTerm' attribute of this object.

getSBOTermID()   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.
Returns
the value of the 'sboTerm' attribute as a string (its value will be of the form 'SBO:NNNNNNN'), or an empty string if the value is not set.
def libsbml.IntraSpeciesReaction.getTypeCode (   self)

Returns the libSBML type code for this SBML object.

getTypeCode()   int
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_. In the Python language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbml. 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_MULTI_BINDING_SITE_SPECIES_TYPE.
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()).

getPackageName()
def libsbml.SBase.getURI (   self)
inherited

Gets the namespace URI to which this element belongs to.

getURI()   string

For example, all elements that belong to SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/core'; all elements that belong to Layout Extension Version 1 for SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/layout/version1'.

This function first returns the URI for this element by looking into the SBMLNamespaces object of the document with the its package name. If not found, it will then look for the namespace associated with the element itself.

Returns
the URI of this element, as a text string.

getSBMLDocument()
getPackageName()
def libsbml.SBase.getVersion (   self)
inherited

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

getVersion()   long
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 version of this SBML object.

getNamespaces()
def libsbml.IntraSpeciesReaction.hasRequiredAttributes (   self)

Returns True if this object has all the required elements.

hasRequiredAttributes()   bool
Returns
True if this object has all the elements required by the package specification; otherwise, False will be returned.
def libsbml.SBase.hasValidLevelVersionNamespaceCombination (   self)
inherited

Predicate returning true if this object's level/version and namespace values correspond to a valid SBML specification.

hasValidLevelVersionNamespaceCombination()   bool

The valid combinations of SBML Level, Version and Namespace as of this release of libSBML are the following:

  • Level 1 Version 2: http://www.sbml.org/sbml/level1
  • Level 2 Version 1: http://www.sbml.org/sbml/level2
  • Level 2 Version 2: http://www.sbml.org/sbml/level2/version2
  • Level 2 Version 3: http://www.sbml.org/sbml/level2/version3
  • Level 2 Version 4: http://www.sbml.org/sbml/level2/version4
  • Level 3 Version 1 Core: http://www.sbml.org/sbml/level3/version1/core
Returns
true if the level, version and namespace values of this SBML object correspond to a valid set of values, false otherwise.
def libsbml.Reaction.initDefaults (   self)
inherited

Initializes the fields of this Reaction object to 'typical' default values.

initDefaults()

The SBML Reaction component has slightly different aspects and default attribute values in different SBML Levels and Versions. This method sets the values to certain common defaults, based mostly on what they are in SBML Level 2. Specifically:

  • Sets the 'reversible' attribute to True
  • Sets the 'fast' attribute to False
  • Marks the 'fast' attribute as not having been set for SBML Level 2, but as having been set for SBML Level 1 and SBML Level 3.
Warning
SBML definitions before SBML Level 2 Version 2 incorrectly indicated that software tools could ignore the 'fast' attribute if they did not implement support for the corresponding concept; however, further research in SBML has revealed that this is not true, and 'fast' cannot be ignored if it is set to True. Beginning with SBML Level 2 Versions 2, the SBML specifications therefore stipulate that if a model has any reactions with 'fast' set to True, a software tool must be able to respect the attribute or else indicate to the user that it does not have the capacity to do so. Readers are directed to the SBML specifications, which provides more detail about the conditions under which a reaction can be considered to be fast in this sense.
def libsbml.SBase.isPackageEnabled (   self,

def libsbml.SBase.isSetAnnotation (   self)
inherited

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

isSetAnnotation()   bool

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.

def libsbml.Reaction.isSetCompartment (   self)
inherited

Predicate returning True if this Reaction's 'compartment' attribute is set.

isSetCompartment()   bool
Returns
True if the 'compartment' attribute of this Reaction is set, False otherwise.
Note
The 'compartment' attribute is available in SBML Level 3, but is not present on Reaction in lower Levels of SBML.
def libsbml.Reaction.isSetFast (   self)
inherited

Predicate returning True if the value of the 'fast' attribute on this Reaction is set.

isSetFast()   bool
In SBML Level 3 Version 2, the 'fast' attribute was removed. All reactions are assumed to be equivalent to reactions in previous levels/versions that have a 'fast' attribute value of False. Users should be aware that even for previous levels/versions of the specification, 'fast' attribute values of True never achieved widespread support, and many software packages may ignore it. To achieve the same or similar effects as setting the fast attribute to True for a given reaction, the KineticLaw attribute should be constructed to produce a value in the desired time scale, or else the reaction could be replaced with an AssignmentRule or AlgebraicRule.
Returns
True if the 'fast' attribute is set, False otherwise.
Warning
SBML definitions before SBML Level 2 Version 2 incorrectly indicated that software tools could ignore the 'fast' attribute if they did not implement support for the corresponding concept; however, further research in SBML has revealed that this is not true, and 'fast' cannot be ignored if it is set to True. Beginning with SBML Level 2 Versions 2, the SBML specifications therefore stipulate that if a model has any reactions with 'fast' set to True, a software tool must be able to respect the attribute or else indicate to the user that it does not have the capacity to do so. Readers are directed to the SBML specifications, which provides more detail about the conditions under which a reaction can be considered to be fast in this sense.
def libsbml.Reaction.isSetId (   self)
inherited

Predicate returning True if this Reaction's 'id' attribute is set.

isSetId()   bool
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.

def libsbml.SBase.isSetIdAttribute (   self)

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:

def libsbml.Reaction.isSetKineticLaw (   self)
inherited

Predicate returning True if this Reaction contains a kinetic law object.

isSetKineticLaw()   bool
Returns
True if a KineticLaw is present in this Reaction,, False otherwise.
def libsbml.SBase.isSetMetaId (   self)
inherited

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

isSetMetaId()   bool
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.

def libsbml.SBase.isSetModelHistory (   self)
inherited

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

isSetModelHistory()   bool
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.
def libsbml.Reaction.isSetName (   self)
inherited

Predicate returning True if this Reaction's 'name' attribute is set.

isSetName()   bool
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.

def libsbml.SBase.isSetNotes (   self)
inherited

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

isSetNotes()   bool

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.

def libsbml.SBase.isSetSBOTerm (   self)
inherited

Predicate returning True if this object's 'sboTerm' attribute is set.

isSetSBOTerm()   bool
Returns
True if the 'sboTerm' attribute of this SBML object is set, False otherwise.
def libsbml.SBase.isSetUserData (   self)
inherited

Predicate returning true or false depending on whether the user data of this element has been set.

isSetUserData()   bool
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.
def libsbml.SBase.matchesRequiredSBMLNamespacesForAddition (   self,
  args 
)
inherited

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

matchesRequiredSBMLNamespacesForAddition(SBase sb)   bool
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.
def libsbml.SBase.matchesSBMLNamespaces (   self,
  args 
)
inherited

Returns True if this object's set of XML namespaces are the same as the given object's XML namespaces.

matchesSBMLNamespaces(SBase sb)   bool
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 the same as sb's, False otherwise.
def libsbml.SBase.removeFromParentAndDelete (   self)
inherited

Removes this object from its parent.

removeFromParentAndDelete()   int

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 possible values returned by this function are:

Owing to the way that language interfaces are created in libSBML, this documentation may show methods that define default values for parameters with text that has the form parameter = value. This is not to be intepreted as a Python keyword argument; the use of a parameter name followed by an equals sign followed by a value is only meant to indicate a default value if the argument is not provided at all. It is not a keyword in the Python sense.
def libsbml.SBase.renameMetaIdRefs (   self,
  oldid,
  newid 
)
inherited

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

renameMetaIdRefs(string oldid, string newid)
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.
def libsbml.Reaction.renameSIdRefs (   self,
  oldid,
  newid 
)
inherited

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

renameSIdRefs(string oldid, string newid)
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.
def libsbml.SBase.renameUnitSIdRefs (   self,
  oldid,
  newid 
)
inherited

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

renameUnitSIdRefs(string oldid, string newid)
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.
def libsbml.SBase.replaceTopLevelAnnotationElement (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

replaceTopLevelAnnotationElement(XMLNode annotation)   int
replaceTopLevelAnnotationElement(string annotation)   int

Each variant is described separately below.


Method variant with the following signature:
replaceTopLevelAnnotationElement(XMLNode annotation)

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 possible values returned by this function are:

removeTopLevelAnnotationElement()
replaceTopLevelAnnotationElement()

Method variant with the following signature:

def libsbml.SBase.setAnnotation (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

setAnnotation(XMLNode annotation)   int
setAnnotation(string annotation)   int

Each variant is described separately below.


Method variant with the following signature:
setAnnotation(XMLNode annotation)

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() or SBase.appendAnnotation().

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. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:

def libsbml.Reaction.setCompartment (   self,
  sid 
)
inherited

Sets the value of the 'compartment' attribute of this Reaction.

setCompartment(string sid)   int

The string sid is copied.

Parameters
sidthe string to use as the compartment of this Reaction.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
The 'compartment' attribute is available in SBML Level 3, but is not present on Reaction in lower Levels of SBML.
def libsbml.Reaction.setFast (   self,
  value 
)
inherited

Sets the value of the 'fast' attribute of this Reaction.

setFast(bool value)   int
In SBML Level 3 Version 2, the 'fast' attribute was removed. All reactions are assumed to be equivalent to reactions in previous levels/versions that have a 'fast' attribute value of False. Users should be aware that even for previous levels/versions of the specification, 'fast' attribute values of True never achieved widespread support, and many software packages may ignore it. To achieve the same or similar effects as setting the fast attribute to True for a given reaction, the KineticLaw attribute should be constructed to produce a value in the desired time scale, or else the reaction could be replaced with an AssignmentRule or AlgebraicRule.

Calling this function with an argument of True for an SBML Level 3 Version 2 Reaction will not set the value, as the attribute does not exist for that level/version.

Parameters
valuethe value of the 'fast' attribute.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Warning
SBML definitions before SBML Level 2 Version 2 incorrectly indicated that software tools could ignore the 'fast' attribute if they did not implement support for the corresponding concept; however, further research in SBML has revealed that this is not true, and 'fast' cannot be ignored if it is set to True. Beginning with SBML Level 2 Versions 2, the SBML specifications therefore stipulate that if a model has any reactions with 'fast' set to True, a software tool must be able to respect the attribute or else indicate to the user that it does not have the capacity to do so. Readers are directed to the SBML specifications, which provides more detail about the conditions under which a reaction can be considered to be fast in this sense.
def libsbml.Reaction.setId (   self,
  sid 
)
inherited

Sets the value of the 'id' attribute of this Reaction.

setId(string sid)   int
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 possible values returned by this function are:

def libsbml.SBase.setIdAttribute (   self,

inherited

def libsbml.Reaction.setKineticLaw (   self,
  kl 
)
inherited

Sets the 'kineticLaw' subelement of this Reaction to a copy of the given KineticLaw object.

setKineticLaw(KineticLaw kl)   int
Parameters
klthe KineticLaw object to use.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.SBase.setMetaId (   self,
  metaid 
)
inherited

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

setMetaId(string metaid)   int
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 possible values returned by this function are:

def libsbml.SBase.setModelHistory (   self,
  history 
)
inherited

Sets the ModelHistory of this object.

setModelHistory(ModelHistory history)   int

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 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.
def libsbml.Reaction.setName (   self,
  name 
)
inherited

Sets the value of the 'name' attribute of this Reaction.

setName(string name)   int

The string in name is copied.

Parameters
namethe new name for the SBML object.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.SBase.setNamespaces (   self,
  xmlns 
)
inherited

Sets the namespaces relevant of this SBML object.

setNamespaces(XMLNamespaces xmlns)   int

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
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.SBase.setNotes (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

setNotes(XMLNode notes)   int
setNotes(string notes, bool addXHTMLMarkup)   int
setNotes(string notes)   int

Each variant is described separately below.


Method variant with the following signature:
setNotes(string notes, bool addXHTMLMarkup = false)

Sets the value of the 'notes' subelement of this SBML object to a copy of the string notes.

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.

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.

1 try:
2  sbmlDoc = SBMLDocument(3, 1)
3 except ValueError:
4  print('Could not create SBMLDocument object')
5  sys.exit(1)
6 
7 note = '<body xmlns='http://www.w3.org/1999/xhtml'><p>here is my note</p></body>'
8 
9 status = sbmlDoc.setNotes(note)
10 if status != LIBSBML_OPERATION_SUCCESS:
11  # Do something to handle the error here.
12  print('Unable to set notes on the SBML document object')
13  sys.exit(1)
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.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.SBase.setSBOTerm (   self,
  args

inherited

This method has multiple variants; they differ in the arguments they accept.

setSBOTerm(int value)   int
setSBOTerm(string sboid)   int

Each variant is described separately below.


Method variant with the following signature:
setSBOTerm(int value)

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 possible values returned by this function are:

def libsbml.SBase.toSBML (   self)
inherited

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

toSBML()   string
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.
def libsbml.SBase.toXMLNode (   self)
inherited

Returns this element as an XMLNode.

toXMLNode()   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.
def libsbml.SBase.unsetAnnotation (   self)
inherited

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

unsetAnnotation()   int

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.

SBML definitions before SBML Level 2 Version 2 incorrectly indicated that software tools could ignore the 'fast' attribute if they did not implement support for the corresponding concept; however, further research in SBML has revealed that this is not true, and 'fast' cannot be ignored if it is set to True. Beginning with SBML Level 2 Versions 2, the SBML specifications therefore stipulate that if a model has any reactions with 'fast' set to True, a software tool must be able to respect the attribute or else indicate to the user that it does not have the capacity to do so. Readers are directed to the SBML specifications, which provides more detail about the conditions under which a reaction can be considered to be fast in this sense.
def libsbml.SBase.unsetId (   self)
inherited

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

unsetId()   int
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.

def libsbml.SBase.unsetIdAttribute (   self)
inherited

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

unsetIdAttribute()   int

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

def libsbml.SBase.unsetMetaId (   self)
inherited

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

unsetMetaId()   int
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 possible values returned by this function are:
def libsbml.SBase.unsetModelHistory (   self)
inherited

Unsets the ModelHistory object attached to this object.

unsetModelHistory()   int
Returns
integer value indicating success/failure of the function. 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.
def libsbml.Reaction.unsetName (   self)
inherited

Unsets the value of the 'name' attribute of this Reaction.

unsetName()   int
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.

def libsbml.SBase.unsetNotes (   self)
inherited

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

unsetNotes()   int

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. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:
