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

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
nodethe node to process

Definition at line 24 of file nodevisitor.cpp.

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

reimplement this method to handle literals.

Parameters
itemthe 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.

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

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

Parameters
nodethe 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.

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

reimplement this method to handle properties.

Parameters
propertythe 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.

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

reimplement this method to handle resources.

Parameters
resourcethe 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.

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

reimplement this method to handle sequences.

Parameters
seqthe sequence to visit
Returns
whether the visitor handled the sequence. Reimplementations of this method must return true.
