Detailed Description

a node type representing simple string values.

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

Definition at line 28 of file literal.h.

Constructor & Destructor Documentation

Literal() [1/3]

Syndication::RDF::Literal::Literal

(

)

creates a null literal.

text() will return a null string.

Definition at line 27 of file literal.cpp.

Literal() [2/3]

Syndication::RDF::Literal::Literal

(

const Literal &

other

)

copies a literal node

Parameters

other

the literal node to copy

Definition at line 32 of file literal.cpp.

Literal() [3/3]

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 51 of file literal.cpp.

~Literal()

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

override

destructor

Definition at line 58 of file literal.cpp.

Member Function Documentation

accept()

void Syndication::RDF::Literal::accept ( NodeVisitor * visitor, NodePtr ptr )

overridevirtual

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 43 of file literal.cpp.

clone()

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

overridevirtual

clones the literal node.

Implements Syndication::RDF::Node.

Definition at line 38 of file literal.cpp.

id()

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

overridevirtual

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 82 of file literal.cpp.

isAnon()

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

overridevirtual

returns false, literals are not anonymous resources

Implements Syndication::RDF::Node.

Definition at line 102 of file literal.cpp.

isLiteral()

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

overridevirtual

returns true for literals

Implements Syndication::RDF::Node.

Definition at line 97 of file literal.cpp.

isNull()

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

overridevirtual

returns whether this node is a null node

Implements Syndication::RDF::Node.

Definition at line 77 of file literal.cpp.

isProperty()

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

overridevirtual

returns false, as a literal is not a property

Implements Syndication::RDF::Node.

Definition at line 92 of file literal.cpp.

isResource()

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

overridevirtual

returns false, as a literal is not a resource

Implements Syndication::RDF::Node.

Definition at line 87 of file literal.cpp.

isSequence()

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

overridevirtual

returns false, literals are not sequences

Implements Syndication::RDF::Node.

Definition at line 107 of file literal.cpp.

operator QString()

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

virtual

implicit conversion to string.

returns text()

Definition at line 117 of file literal.cpp.

operator=()

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

virtual

assigns another literal

Parameters

other

the literal to assign

Definition at line 62 of file literal.cpp.

operator==()

bool Syndication::RDF::Literal::operator==

(

const Literal &

other

)

const

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

Definition at line 68 of file literal.cpp.

setId()

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

overridevirtual

used in Model

Implements Syndication::RDF::Node.

Definition at line 126 of file literal.cpp.

setModel()

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

overridevirtual

used in Model

Implements Syndication::RDF::Node.

Definition at line 122 of file literal.cpp.

text()

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

overridevirtual

the string value of the literal

Implements Syndication::RDF::Node.

Definition at line 112 of file literal.cpp.
