Abstract:
A method for supplying a state change associated with remote objects in a distributed system comprised of multiple platforms, wherein computational entities maintain references indicating the location of objects within the distributed system, the method comprising:providing an object resident on a first platform; registering a request from a computational entity located on a second platform remote with respect to the first platform to receive an indication reflecting a state change associated with the object, wherein the registering step is performed by a processor operating in the second platform and includes: receiving a strong reference to the object from the computational entity, and creating a remote weak reference corresponding to the object based on the received strong reference; determining whether an event has occurred changing the state associated with the object; locating the one of the platforms upon which the object resides based on the remote weak reference corresponding to the object; sending a status request to the located platform; and providing a notification to the computational entity based on the determination.
