  +--javax.telephony.media.provider.NullMediaGroup

All Implemented Interfaces:

MediaConstants, MediaServiceConstants, MPI.MediaGroup, MPI.Resource

public class NullMediaGroup

extends java.lang.Object

implements MPI.MediaGroup, MediaServiceConstants

A MediaGroup implementation. Just done-ify the events, and return null.

A working MediaGroup should find or create real objects and create Exceptions if necessary. This class can be used as a source code "template", one is not expected to use it as a base class.

Since:

JTAPI-1.4
