Detailed Description

Resources are the entities in the RDF graph.

In RSS, e.g. the feed channel itself and the items are resources.

Constructor & Destructor Documentation

Resource() [1/3]

Resource::Resource

(

)

creates a null resource

Definition at line 48 of file resource.cpp.

Resource() [2/3]

Resource::Resource

(

const Resource &

other

)

copies a resource

Parameters

other

the resource to copy

Definition at line 42 of file resource.cpp.

Resource() [3/3]

Resource::Resource ( const QString & uri )

explicit

creates a resource with a given URI.

Do not use this directly, use Model::createResource() instead.

Parameters

uri	the URI of the new resource

~Resource()

Resource::~Resource ( )

override

destructor

Definition at line 67 of file resource.cpp.

Member Function Documentation

accept()

void Resource::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.

Reimplemented in Syndication::RDF::Sequence.

Definition at line 128 of file resource.cpp.

clone()

Resource * Resource::clone ( ) const

overridevirtual

creates a copy of the resource object

Implements Syndication::RDF::Node.

Reimplemented in Syndication::RDF::Sequence.

Definition at line 123 of file resource.cpp.

hasProperty()

bool Resource::hasProperty ( PropertyPtr property ) const

virtual

returns whether the resource has a property property in the associated model.

Parameters

property

the property to check for

Definition at line 85 of file resource.cpp.

id()

unsigned int Resource::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 136 of file resource.cpp.

isAnon()

bool Resource::isAnon ( ) const

overridevirtual

returns whether this resource is an anonymous resource

Implements Syndication::RDF::Node.

Definition at line 178 of file resource.cpp.

isLiteral()

bool Resource::isLiteral ( ) const

overridevirtual

returns false

Implements Syndication::RDF::Node.

Definition at line 173 of file resource.cpp.

isNull()

bool Resource::isNull ( ) const

overridevirtual

returns whether the resource is a null resource

Implements Syndication::RDF::Node.

Definition at line 141 of file resource.cpp.

isProperty()

bool Resource::isProperty ( ) const

overridevirtual

returns true if this resource is also a property, false otherwise

Implements Syndication::RDF::Node.

Definition at line 168 of file resource.cpp.

isResource()

bool Resource::isResource ( ) const

overridevirtual

returns true

Implements Syndication::RDF::Node.

Definition at line 163 of file resource.cpp.

isSequence()

bool Resource::isSequence ( ) const

overridevirtual

returns true if this resource is also a sequence, false otherwise.

Implements Syndication::RDF::Node.

Reimplemented in Syndication::RDF::Sequence.

Definition at line 183 of file resource.cpp.

model()

Model Resource::model ( ) const

virtual

the model this resource belongs to

Definition at line 146 of file resource.cpp.

operator=()

Resource & Resource::operator=

(

const Resource &

other

)

assigns a resource

Parameters

other

the resource to assign

Definition at line 71 of file resource.cpp.

operator==()

bool Resource::operator==

(

const Resource &

other

)

const

checks two resources for equality.

Currently both URI (or anonID) and id() must be equal!

Parameters

other

the node to compare this node to

Definition at line 77 of file resource.cpp.

properties()

QList< StatementPtr > Resource::properties ( PropertyPtr property ) const

virtual

returns the list of all statements from the associated model where this resource is the subject and the given property the predicate.

Parameters

property

the property to check for

Returns

a list of the statements that satisfy the conditions.

Definition at line 110 of file resource.cpp.

property()

StatementPtr Resource::property ( PropertyPtr property ) const

virtual

returns a statement from the associated model where this resource is the subject and the given property the predicate.

Parameters

property

the property to check for

Returns

the first statement found that satisfies the conditions. If there are multiple statements, an arbitrary one is returned.

Definition at line 97 of file resource.cpp.

setId()

void Resource::setId ( unsigned int id )

overridevirtual

used in Model

Implements Syndication::RDF::Node.

Definition at line 195 of file resource.cpp.

setModel()

void Resource::setModel ( const Model & model )

overridevirtual

used in Model

Implements Syndication::RDF::Node.

Definition at line 202 of file resource.cpp.

uri()

QString Resource::uri ( ) const

virtual

returns the URI of the resource

Definition at line 207 of file resource.cpp.
