Inheritance diagram for SBMLExtensionNamespaces< SBMLExtensionType >:

Detailed Description

template<class SBMLExtensionType>
class SBMLExtensionNamespaces< SBMLExtensionType >

Set of SBML Level + Version + namespace triples.

This class of objects is defined by libSBML only and has no direct equivalent in terms of SBML components. This class is not prescribed by the SBML specifications, although it is used to implement features defined in SBML.

SBMLExtensionNamespaces is a template class. It is extended from SBMLNamespaces and is meant to be used by package extensions to store the SBML Level, Version within a Level, and package version of the SBML Level 3 package implemented by a libSBML package extension.

How to use SBMLExtensionNamespaces for a package implementation

: Each package extension in libSBML needs to extend and instantiate the template class SBMLExtensionNamespaces, as well as declare a specific typedef. The following sections explain these steps in detail.

1. Define the typedef

Each package needs to declare a package-specific version of the SBMLExtensionNamespaces class using a typedef. The following example code demonstrates how this is done in the case of the Layout package:

typedef SBMLExtensionNamespaces<LayoutExtension> LayoutPkgNamespaces;

This creates a new type called LayoutPkgNamespaces. The code above is usually placed in the same file that contains the SBMLExtension-derived definition of the package extension base class. In the case of the Layout package, this is in the file src/packages/layout/extension/LayoutExtension.h in the libSBML source distribution.

2. Instantiate a template instance

Each package needs to instantiate a template instance of the SBMLExtensionNamespaces class. The following example code demonstrates how this is done in the case of the Layout package:

template class LIBSBML_EXTERN SBMLExtensionNamespaces<LayoutExtension>;

In the case of the Layout package, the code above is located in the file src/packages/layout/extension/LayoutExtension.cpp in the libSBML source distribution.

3. Create constructors that accept the class

Each SBase-derived class in the package extension should implement a constructor that accepts the SBMLExtensionNamespaces-derived class as an argument. For example, in the Layout package, the class BoundBox has a constructor declared as follows

BoundingBox(LayoutPkgNamespaces* layoutns);

The implementation of this constructor must, among other things, take the argument namespace object and use it to set the XML namespace URI for the object. Again, for the BoundingBox example:

BoundingBox::BoundingBox(LayoutPkgNamespaces* layoutns)
 : SBase(layoutns)
  ,mPosition(layoutns)
  ,mDimensions(layoutns)
  ,mPositionExplicitlySet (false)
  ,mDimensionsExplicitlySet (false)
{
  // Standard extension actions.
  setElementNamespace(layoutns->getURI());
  connectToChild();
  // Package-specific actions.
  mPosition.setElementName("position");
  // Load package extensions bound with this object (if any).
  loadPlugins(layoutns);
}

XMLNamespaces * SBMLNamespaces::getNamespaces ( )

inherited

Get the XML namespaces list for this SBMLNamespaces object.

: SBMLNamespaces objects are used in libSBML to communicate SBML Level and Version data between constructors and other methods. The SBMLNamespaces object class holds triples consisting of SBML Level, Version, and the corresponding SBML XML namespace. Most constructors for SBML objects in libSBML take a SBMLNamespaces object as an argument, thereby allowing the constructor to produce the proper combination of attributes and other internal data structures for the given SBML Level and Version.

The plural name (SBMLNamespaces) is not a mistake, because in SBML Level 3, objects may have extensions added by Level 3 packages used by a given model and therefore may have multiple namespaces associated with them. In SBML Levels below Level 3, the SBMLNamespaces object only records one SBML Level/Version/namespace combination at a time. Most constructors for SBML objects in libSBML take a SBMLNamespaces object as an argument, thereby allowing the constructor to produce the proper combination of attributes and other internal data structures for the given SBML Level and Version.

Returns: the XML namespaces of this SBMLNamespaces object.
