Interface Alt

All Superinterfaces:

All Known Implementing Classes:
AltImpl

public interface Alt extends Container

An RDF Alternative container.

This interface defines methods for accessing RDF Alternative resources. These methods operate on the RDF statements contained in a model. The Alternative implementation may cache state from the underlying model, so objects should not be added to or removed from the Alternative by directly manipulating its properties, whilst the Alternative is being accessed through this interface.

When a member is deleted from an Alternative using this interface, or an iterator returned through this interface, all the other members with higher ordinals are renumbered using an implementation dependent algorithm.

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.

      remove in interface Container
      Parameters:
      s - The statement to be removed from the model.
      Returns:
      this container to enable cascading calls.
