All known Subclasses: com.hp.hpl.jena.rdf.model.impl.ResourceImpl,
| Resource | | public interface Resource extends RDFNode(Code) | | An RDF Resource.
Resource instances when created may be associated with a specific model.
Resources created by a model will refer to that model, and support
a range of methods, such as getProperty() and
addProperty() which will access or modify that model. This
enables the programmer to write code in a compact and easy style.
Resources created by ResourceFactory will not refer to any model, and will
not permit operations which require a model. Such resources are useful
as general constants.
This interface provides methods supporting typed literals. This means
that methods are provided which will translate a built in type, or an
object to an RDF Literal. This translation is done by invoking the
toString() method of the object, or its built in equivalent.
The reverse translation is also supported. This is built in for built
in types. Factory objects, provided by the application, are used
for application objects.
This interface provides methods for supporting enhanced resources. An
enhanced resource is a resource to which the application has added
behaviour. RDF containers are examples of enhanced resources built in
to this package. Enhanced resources are supported by encapsulating a
resource created by an implementation in another class which adds
the extra behaviour. Factory objects are used to construct such
enhanced resources.
