Detailed Description

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

Definition at line 31 of file node.h.

Constructor & Destructor Documentation

◆ ~Node()

Node::~Node ( )
virtual

Definition at line 22 of file node.cpp.

Member Function Documentation

◆ accept()

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

Used by visitors for double dispatch.

See NodeVisitor for more information.

Parameters
visitorthe visitor calling the method
ptra 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

◆ setModel()

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

◆ 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.
