XMLTriple Class Reference

Detailed Description

A qualified XML name.

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.

A "triple" in the libSBML XML layer encapsulates the notion of qualified name, meaning an element name or an attribute name with an optional namespace qualifier. Triples by themselves are not entities in an XML stream—they are not, for example, elements or attributes; rather, XMLTriple is used in libSBML to construct these other kinds of objects.

An XMLTriple instance carries up to three data items:

1. The name of the attribute or element; that is, the attribute name as it appears in an XML document or data stream;
2. The XML namespace prefix (if any) of the attribute. For example, in the following fragment of XML, the namespace prefix is the string mysim and it appears on both the element someelement and the attribute attribA. When both the element and the attribute are stored as XMLTriple objects, their prefix is mysim.

   <mysim:someelement mysim:attribA="value" />
   

3. The XML namespace URI with which the prefix is associated. In XML, every namespace used must be declared and mapped to a URI.

XMLTriple objects are the lowest-level data item in the XML layer of libSBML. Other objects such as XMLToken make use of XMLTriple objects.

Constructor & Destructor Documentation

XMLTriple() [1/4]

XMLTriple::XMLTriple

(

)

Creates a new, empty XMLTriple object.

XMLTriple() [2/4]

XMLTriple::XMLTriple	(	const std::string &	name,
		const std::string &	uri,
		const std::string &	prefix
	)

Creates a new XMLTriple object with a given name, uri and and prefix.

Parameters

name	a string, the name for the entity represented by this object.
uri	a string, the XML namespace URI associated with the prefix.
prefix	a string, the XML namespace prefix for this triple.

XMLTriple() [3/4]

XMLTriple::XMLTriple	(	const std::string &	triplet,
		const char	sepchar = ' '
	)

Creates an XMLTriple object by splitting a given string at a given separator character.

The "triplet" in this case is a string that may be in one of the following three possible formats:

1. name
2. URIxname
3. URIxnamexprefix

where x represents the separator character, sepchar.

Parameters

triplet	a string representing the triplet as shown above.
sepchar	a character, the sepchar used in the triplet.

XMLTriple() [4/4]

XMLTriple::XMLTriple

(

const XMLTriple &

orig

)

Copy constructor; creates a copy of this XMLTriple object.

Parameters

orig	the XMLTriple object to copy.

~XMLTriple()

XMLTriple::~XMLTriple

(

)

Destructor.
