Detailed Description

a node type representing simple string values.

Literals can be object of statement, but neither subject nor predicate.

Definition at line 44 of file literal.h.

Constructor & Destructor Documentation

Syndication::RDF::Literal::Literal

(

)

creates a null literal.

text() will return a null string.

Definition at line 44 of file literal.cpp.

Syndication::RDF::Literal::Literal

(

const Literal &

other

)

copies a literal node

Parameters

other

the literal node to copy

Definition at line 48 of file literal.cpp.

Syndication::RDF::Literal::Literal ( const QString &  text )

explicit

creates a new literal node with a given text

Parameters

text	the literal string

Definition at line 65 of file literal.cpp.

Syndication::RDF::Literal::~Literal ( )

virtual

destructor

Definition at line 71 of file literal.cpp.

Member Function Documentation

void Syndication::RDF::Literal::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 from Syndication::RDF::Node.

Definition at line 58 of file literal.cpp.

Literal * Syndication::RDF::Literal::clone ( ) const

virtual

clones the literal node.

Implements Syndication::RDF::Node.

Definition at line 53 of file literal.cpp.

unsigned int Syndication::RDF::Literal::id ( ) const

virtual

the identifier of this node.

the ID is unique per model and set by the associated model at creation time.

Implements Syndication::RDF::Node.

Definition at line 98 of file literal.cpp.

bool Syndication::RDF::Literal::isAnon ( ) const

virtual

returns false, literals are not anonymous resources

Implements Syndication::RDF::Node.

Definition at line 118 of file literal.cpp.

bool Syndication::RDF::Literal::isLiteral ( ) const

virtual

returns true for literals

Implements Syndication::RDF::Node.

Definition at line 113 of file literal.cpp.

bool Syndication::RDF::Literal::isNull ( ) const

virtual

returns whether this node is a null node

Implements Syndication::RDF::Node.

Definition at line 93 of file literal.cpp.

bool Syndication::RDF::Literal::isProperty ( ) const

virtual

returns false, as a literal is not a property

Implements Syndication::RDF::Node.

Definition at line 108 of file literal.cpp.

bool Syndication::RDF::Literal::isResource ( ) const

virtual

returns false, as a literal is not a resource

Implements Syndication::RDF::Node.

Definition at line 103 of file literal.cpp.

bool Syndication::RDF::Literal::isSequence ( ) const

virtual

returns false, literals are not sequences

Implements Syndication::RDF::Node.

Definition at line 123 of file literal.cpp.

Syndication::RDF::Literal::operator QString ( ) const

virtual

implicit conversion to string.

returns text()

Definition at line 133 of file literal.cpp.

Literal & Syndication::RDF::Literal::operator= ( const Literal &  other )

virtual

assigns another literal

Parameters

other

the literal to assign

Definition at line 75 of file literal.cpp.

bool Syndication::RDF::Literal::operator== ( const Node &  other ) const

virtual

two literal nodes are equal iff their text and ID's are equal.

Implements Syndication::RDF::Node.

Definition at line 81 of file literal.cpp.

void Syndication::RDF::Literal::setId ( unsigned int  id )

virtual

used in Model

Implements Syndication::RDF::Node.

Definition at line 142 of file literal.cpp.

void Syndication::RDF::Literal::setModel ( const Model &  model )

virtual

used in Model

Implements Syndication::RDF::Node.

Definition at line 138 of file literal.cpp.

QString Syndication::RDF::Literal::text ( ) const

virtual

the string value of the literal

Implements Syndication::RDF::Node.
