Detailed Description

Visitor interface, following the Visitor design pattern.

Use this if you want to process nodes and the way how to handle the nodes depends on it's concrete type (e.g. Resource or Literal).

Member Function Documentation

visit()

void Syndication::RDF::NodeVisitor::visit ( NodePtr node )

virtual

call this method to handle a node.

Depending on the concrete type of the node, a specialized visit method is called.

Parameters

node	the node to process

Definition at line 24 of file nodevisitor.cpp.

visitLiteral()

bool Syndication::RDF::NodeVisitor::visitLiteral ( LiteralPtr )

virtual

reimplement this method to handle literals.

Parameters

item	the literal to visit

Returns

whether the visitor handled the literal. Reimplementations of this method must return true.

Definition at line 29 of file nodevisitor.cpp.

visitNode()

bool Syndication::RDF::NodeVisitor::visitNode ( NodePtr node )

virtual

reimplement this method to handle nodes that weren't handled by the more specific method.

Parameters

node	the node to visit

Returns

whether the visitor handled the node. Reimplementations of this method must return true.

Definition at line 34 of file nodevisitor.cpp.

visitProperty()

bool Syndication::RDF::NodeVisitor::visitProperty ( PropertyPtr property )

virtual

reimplement this method to handle properties.

Parameters

property

the property to visit

Returns

whether the visitor handled the property. Reimplementations of this method must return true.

Definition at line 39 of file nodevisitor.cpp.

visitResource()

bool Syndication::RDF::NodeVisitor::visitResource ( ResourcePtr resource )

virtual

reimplement this method to handle resources.

Parameters

resource

the resource to visit

Returns

whether the visitor handled the resource. Reimplementations of this method must return true.

Definition at line 44 of file nodevisitor.cpp.

visitSequence()

bool Syndication::RDF::NodeVisitor::visitSequence ( SequencePtr seq )

virtual

reimplement this method to handle sequences.

Parameters

seq	the sequence to visit

Returns

whether the visitor handled the sequence. Reimplementations of this method must return true.
