Detailed Description

An object handle for duplicated objects.

This object handle is a reference object handle for object who have more than one reference object ( duplicated objects and the controller). This implementation id concerned with the propagation of events to the other reference objects.

Version:
1.0 (warning, not implementing dynamic discovery of sites the object is duplicated on. All sites are supposed)
