| void Syndication::RDF::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.
| 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.
| 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.
| 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.
| 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.
| 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.
| 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.
| 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.
| 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.
| 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
| virtual void Syndication::RDF::Node::setId | ( | unsigned int | id | ) | [pure virtual] |
used in Model
For internal use only.
Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.
| virtual void Syndication::RDF::Node::setModel | ( | const Model & | model | ) | [pure virtual] |
used in Model
For internal use only.
Implemented in Syndication::RDF::Literal, and Syndication::RDF::Resource.
| 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.
