Detailed Description

An RDF model, a set of RDF statements.

Model objects are implicitely shared.

Constructor & Destructor Documentation

Syndication::RDF::Model::Model

(

)

default constructor, creates an empty model containing no statements

Definition at line 31 of file model.cpp.

Syndication::RDF::Model::Model

(

const Model &

other

)

constructs a model from another.

Both models will share the same set of statements, so adding/removing statements from one model also modifies the other!

Parameters

other

another model

Definition at line 35 of file model.cpp.

Syndication::RDF::Model::~Model ( )

virtual

destructor

Member Function Documentation

StatementPtr Syndication::RDF::Model::addStatement ( ResourcePtr  subject, PropertyPtr  predicate, NodePtr  object  )

virtual

adds a statement to the model.

Parameters

subject
predicate
object

Returns

a shared pointer to a statement associated with this model, with the given subject, predicate and object

Definition at line 146 of file model.cpp.

LiteralPtr Syndication::RDF::Model::createLiteral ( const QString &  text )

virtual

creates a literal and associates it with this model.

Parameters

text	the literal text

Returns

a shared pointer to the requested literal

Definition at line 123 of file model.cpp.

PropertyPtr Syndication::RDF::Model::createProperty ( const QString &  uri )

virtual

creates a property and associates it with this model.

If the model already contains a property with the given URI, the existing instance is returned.

Parameters

uri	the URI of the property. This must be non-empty, otherwise null property is returned

Returns

a shared pointer to the requested property

Definition at line 55 of file model.cpp.

ResourcePtr Syndication::RDF::Model::createResource ( const QString &  uri = QString() )

virtual

creates a resource and associates it with this model.

If the model already contains a resource with the given URI, the existing instance is returned.

Parameters

uri	the URI of the resource. If a null string, a blank node is created.

Returns

a shared pointer to the requested resource

Definition at line 80 of file model.cpp.

SequencePtr Syndication::RDF::Model::createSequence ( const QString &  uri = QString() )

virtual

creates a sequence and associates it with this model.

If the model already contains a sequence with the given URI, the existing instance is returned.

Parameters

uri	the URI of the sequence, or a null string for an anonymous instance

Returns

a shared pointer to the requested sequence

Definition at line 98 of file model.cpp.

QString Syndication::RDF::Model::debugInfo ( ) const

virtual

/** a debug string listing the contained statements for debugging purposes

Returns

debug string

Definition at line 274 of file model.cpp.

bool Syndication::RDF::Model::isEmpty ( ) const

virtual

returns whether this model is empty, i.e.

contains no statements.

Definition at line 198 of file model.cpp.

LiteralPtr Syndication::RDF::Model::literalByID ( uint  id ) const

virtual

searches the model for a literal by ID.

Parameters

id	the ID to search for

Returns

the literal with the given ID, or a null literal if the model doesn't contain a literal with this ID

Definition at line 376 of file model.cpp.

NodePtr Syndication::RDF::Model::nodeByID ( uint  id ) const

virtual

searches the model for a node by ID.

Parameters

id	the ID to search for

Returns

the node with the given ID, or a null node (which is of type Literal) if the model doesn't contain the node with this ID

Definition at line 317 of file model.cpp.

Model & Syndication::RDF::Model::operator=

(

const Model &

other

)

assigns another model.

Both models will share the same set of statements, so adding/removing statements from one model also modifies the other!

Parameters

other

another model

Definition at line 44 of file model.cpp.

bool Syndication::RDF::Model::operator==

(

const Model &

other

)

const

Returns whether two models objects represent the same model (i.e.

share the same underlying statement set). Currently this method does not compare the statement list. Two indepently created models containing the same statements are not equal!

Parameters

other

the model to compare to

Definition at line 50 of file model.cpp.

PropertyPtr Syndication::RDF::Model::propertyByID ( uint  id ) const

virtual

searches the model for a property by ID.

Parameters

id	the ID to search for

Returns

the property with the given ID, or a null property if the model doesn't contain a property with this ID

Definition at line 355 of file model.cpp.

void Syndication::RDF::Model::removeStatement ( ResourcePtr  subject, PropertyPtr  predicate, NodePtr  object  )

virtual

removes a statement from the model.

Parameters

subject	subject of the statement
predicate	predicate of the statement
object	object of the statement

Definition at line 137 of file model.cpp.

void Syndication::RDF::Model::removeStatement ( StatementPtr  statement )

virtual

removes a statement from the model.

Parameters

statement

the statement to remove

Definition at line 132 of file model.cpp.

ResourcePtr Syndication::RDF::Model::resourceByID ( uint  id ) const

virtual

searches the model for a resource by ID.

Parameters

id	the ID to search for

Returns

the resource with the given ID, or a null resource if the model doesn't contain a resource with this ID

Definition at line 334 of file model.cpp.

QList< ResourcePtr > Syndication::RDF::Model::resourcesWithType ( ResourcePtr  type ) const

virtual

returns all resources of a given type.

subClassOf semantics are ignored.

Parameters

type	a resource representing an RDFS class

Definition at line 300 of file model.cpp.

QList< StatementPtr > Syndication::RDF::Model::statements ( ) const

virtual

returns a list of the statements in this model.

Definition at line 269 of file model.cpp.
