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 | ) |
◆ Resource() [3/3]
|
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
Definition at line 53 of file resource.cpp.
◆ ~Resource()
|
override |
destructor
Definition at line 67 of file resource.cpp.
Member Function Documentation
◆ accept()
|
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()
|
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()
|
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()
|
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()
|
overridevirtual |
returns whether this resource is an anonymous resource
Implements Syndication::RDF::Node.
Definition at line 178 of file resource.cpp.
◆ isLiteral()
|
overridevirtual |
◆ isNull()
|
overridevirtual |
returns whether the resource is a null resource
Implements Syndication::RDF::Node.
Definition at line 141 of file resource.cpp.
◆ isProperty()
|
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()
|
overridevirtual |
◆ isSequence()
|
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()
|
virtual |
the model this resource belongs to
Definition at line 146 of file resource.cpp.
◆ operator=()
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()
|
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()
|
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()
|
overridevirtual |
◆ setModel()
|
overridevirtual |
◆ text()
|
overridevirtual |
returns a null string
Implements Syndication::RDF::Node.
Definition at line 202 of file resource.cpp.
◆ uri()
|
virtual |
returns the URI of the resource
