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

Reimplemented in Syndication::RDF::Literal, Syndication::RDF::Property, Syndication::RDF::Resource, and Syndication::RDF::Sequence.

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

Implemented in Syndication::RDF::Literal, Syndication::RDF::Property, Syndication::RDF::Resource, and Syndication::RDF::Sequence.

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.

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.

isAnon()

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

pure virtual

returns whether this node is an anonymous resource

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.

isLiteral()

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

pure virtual

returns whether this node is a literal

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.

isNull()

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

pure virtual

returns whether this node is a null node

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.

isProperty()

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

pure virtual

returns whether this node is a property

Implemented in Syndication::RDF::Literal, Syndication::RDF::Property, and Syndication::RDF::Resource.

isResource()

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

pure virtual

returns whether this node is a resource

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.

isSequence()

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

pure virtual

returns whether this node is an RDF sequence

Implemented in Syndication::RDF::Literal, Syndication::RDF::Resource, and Syndication::RDF::Sequence.

setId()

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

pure virtual

used in Model

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.

setModel()

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

pure virtual

used in Model

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.

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.

Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.
