Detailed Description

comp Extension of SBMLDocument.

The CompSBMLDocumentPlugin class inherits from the SBMLDocumentPlugin class, and codifies the extensions to the SBMLDocument class defined in the SBML Level 3 Hierarchical Model Composition (“comp”) package. This extension allows multiple Model objects to be defined in a single SBMLDocument, stored in an optional child ListOfModelDefinitions object, as well as define references to Model objects in other files, stored in the optional child ListOfExternalModelDefinitions object. These model definitions, if present, allow Submodel objects to reference other Models to instantiate.

The presence of any ModelDefinition or ExternalModelDefinition in an SBMLDocument does not change the default Model in the file. If a SBMLDocument is submitted somewhere to be simulated, it is still the <model> child of the <sbml> element that should be simulated.

In addition, as all packages do, the CompSBMLDocumentPlugin defines a required flag named required, which indicates whether “comp” constructs can be used to change the core mathematics of the <model> child of the <sbml> element. Because they can, this attribute must be set True.

Constructor & Destructor Documentation

def libsbml.CompSBMLDocumentPlugin.__init__ (   self,
  args 
)

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

__init__(string uri, string prefix, CompPkgNamespaces compns)   CompSBMLDocumentPlugin
__init__(CompSBMLDocumentPlugin orig)   CompSBMLDocumentPlugin

Each variant is described separately below.


Method variant with the following signature:
CompSBMLDocumentPlugin(string uri, string prefix, CompPkgNamespaces compns)

Creates a new CompSBMLDocumentPlugin object using the given parameters.

In the XML representation of an SBML document, XML namespaces are used to identify the origin of each XML construct used. XML namespaces are identified by their unique resource identifiers (URIs). The core SBML specifications stipulate the namespaces that must be used for core SBML constructs; for example, all XML elements that belong to SBML Level 3 Version 1 Core must be placed in the XML namespace identified by the URI 'http://www.sbml.org/sbml/level3/version1/core'. Individual SBML Level 3 packages define their own XML namespaces; for example, all elements belonging to the SBML Level 3 Layout Version 1 package must be placed in the XML namespace 'http://www.sbml.org/sbml/level3/version1/layout/version1/'.
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
urithe URI of the SBML Level 3 package implemented by this libSBML package extension.
prefixthe XML namespace prefix being used for the package.
compnsthe namespaces object for the package.

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

def libsbml.SBMLDocumentPlugin.getRequired (   self)
inherited

Returns the value of the 'required' attribute.

getRequired()   bool
SBML Level 3 requires that every package defines an attribute named 'required' on the root <sbml> element in an SBML file or data stream. The attribute, being in the namespace of the Level 3 package in question, must be prefixed by the XML namespace prefix associated with the package. The value of the 'required' attribute indicates whether constructs in that package may change the mathematical interpretation of constructs defined in SBML Level 3 Core. A 'required' value of True indicates that the package may do so. The value of the attribute is set by the Level 3 package specification, and does not depend on the actual presence or absence of particular package constructs in a given SBML document: in other words, if the package specification defines any construct that can change the model's meaning, the value of the 'required' attribute must always be set to True in any SBML document that uses the package.

The XML namespace declaration for an SBML Level 3 package is an indication that a model makes use of features defined by that package, while the 'required' attribute indicates whether the features may be ignored without compromising the mathematical meaning of the model. Both are necessary for a complete reference to an SBML Level 3 package.

Returns
the bool value of 'required' attribute for the SBML package.

def libsbml.SBasePlugin.getSBMLDocument (   self,
  args 
)
inherited

Returns the SBMLDocument object containing this object instance.

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
the parent SBMLDocument object of this plugin object.
See also
getParentSBMLObject()
def libsbml.SBasePlugin.getURI (   self)
inherited

Returns the XML namespace URI for the package to which this object belongs.

getURI()   string
In the XML representation of an SBML document, XML namespaces are used to identify the origin of each XML construct used. XML namespaces are identified by their unique resource identifiers (URIs). The core SBML specifications stipulate the namespaces that must be used for core SBML constructs; for example, all XML elements that belong to SBML Level 3 Version 1 Core must be placed in the XML namespace identified by the URI 'http://www.sbml.org/sbml/level3/version1/core'. Individual SBML Level 3 packages define their own XML namespaces; for example, all elements belonging to the SBML Level 3 Layout Version 1 package must be placed in the XML namespace 'http://www.sbml.org/sbml/level3/version1/layout/version1/'.

This method first looks into the SBMLNamespaces object possessed by the parent SBMLDocument object of the current object. If this cannot be found, this method returns the result of getElementNamespace().

Returns
a string, the URI of the XML namespace to which this object belongs.

isSetRequired()   bool
SBML Level 3 requires that every package defines an attribute named 'required' on the root <sbml> element in an SBML file or data stream. The attribute, being in the namespace of the Level 3 package in question, must be prefixed by the XML namespace prefix associated with the package.

def libsbml.SBasePlugin.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.SBasePlugin.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.SBasePlugin.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.SBasePlugin.setElementNamespace (   self,
  uri 
)
inherited

Sets the XML namespace to which this object belongs.

setElementNamespace(string uri)   int
In the XML representation of an SBML document, XML namespaces are used to identify the origin of each XML construct used. XML namespaces are identified by their unique resource identifiers (URIs). The core SBML specifications stipulate the namespaces that must be used for core SBML constructs; for example, all XML elements that belong to SBML Level 3 Version 1 Core must be placed in the XML namespace identified by the URI 'http://www.sbml.org/sbml/level3/version1/core'. Individual SBML Level 3 packages define their own XML namespaces; for example, all elements belonging to the SBML Level 3 Layout Version 1 package must be placed in the XML namespace 'http://www.sbml.org/sbml/level3/version1/layout/version1/'.
Parameters
urithe URI to assign to 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:

getElementNamespace()
def libsbml.CompSBMLDocumentPlugin.setRequired (   self,
  value 
)

Sets the bool value of 'required' attribute of corresponding package in SBMLDocument element.

setRequired(bool value)   int
