Detailed Description

an RDF node, abstract baseclass for all RDF node types, like resources and literals

Definition at line 30 of file node.h.

Node::~Node ( )

virtual

Member Function Documentation

accept()

void Node::accept ( NodeVisitor *  visitor, NodePtr  ptr  )

virtual

Used by visitors for double dispatch.

See NodeVisitor for more information.

Parameters

visitor	the visitor calling the method
ptr	a shared pointer object for this node

Definition at line 17 of file node.cpp.

clone()

virtual Node* Syndication::RDF::Node::clone ( ) const

pure virtual

returns a copy of the object.

Must be implemented by subclasses to return a copy using the concrete type

id()

virtual unsigned int Syndication::RDF::Node::id ( ) const

pure virtual

the identifier of this node.

the ID is unique per model and set by the associated model at creation time.

isAnon()

virtual bool Syndication::RDF::Node::isAnon ( ) const

pure virtual

returns whether this node is an anonymous resource

isLiteral()

virtual bool Syndication::RDF::Node::isLiteral ( ) const

pure virtual

returns whether this node is a literal

isNull()

virtual bool Syndication::RDF::Node::isNull ( ) const

pure virtual

returns whether this node is a null node

isProperty()

virtual bool Syndication::RDF::Node::isProperty ( ) const

pure virtual

returns whether this node is a property

isResource()

virtual bool Syndication::RDF::Node::isResource ( ) const

pure virtual

returns whether this node is a resource

isSequence()

virtual bool Syndication::RDF::Node::isSequence ( ) const

pure virtual

returns whether this node is an RDF sequence

operator==()

virtual bool Syndication::RDF::Node::operator== ( const Node &  other ) const

pure virtual

checks whether two nodes are equal.

The meaning of equality is defined per subclass (e.g. equality of URIs, IDs etc.)

Parameters

other

the node to compare to

setId()

virtual void Syndication::RDF::Node::setId ( unsigned int  id )

pure virtual

used in Model

setModel()

virtual void Syndication::RDF::Node::setModel ( const Model &  model )

pure virtual

used in Model

text()

virtual QString Syndication::RDF::Node::text ( ) const

pure virtual

returns a textual representation of the node.

This is the literal string for literals, and a null string for other node types.
