An RDF Container.
This interface defines methods for accessing RDF container resources.
These methods operate on the RDF statements contained in a model. The
container implementation may cache state from the underlying model, so
objects should not be added to or removed from the container by directly
manipulating its properties, whilst the container is being
accessed through this interface.
When a member is deleted from a container using this interface, or an
iterator returned through this interface, all the other members with
higher ordinals are renumbered using an algorithm which may depend on the
type of the container.
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.
