Method Detail

remoteReferenceUnmarshaled

public void remoteReferenceUnmarshaled(SingleRemoteClientRef ref)

Description copied from class: DGCUnmarshalContext

Called by a SingleRemoteClientRef object if it is deserialized and the dgc object is not local.

Specified by:

remoteReferenceUnmarshaled in class DGCUnmarshalContext

localReferenceUnmarshaled

public void localReferenceUnmarshaled(SingleRemoteClientRef ref)

Description copied from class: DGCUnmarshalContext

Called by a SingleRemoteClientRef object if it is deserialized and the dgc object is local.

Specified by:

localReferenceUnmarshaled in class DGCUnmarshalContext

reset

public boolean reset()

Description copied from class: DGCUnmarshalContext

Reset method. When the reset() method returns all received remote references are registered with the DGC algorithm. It returns true if an ACK Message must be sent to the sender. The reset() method and the corresponding done() method on the sending side must return the same value. That means that sender and receiver must always agree if an ACK message is required or not. This method also resets the context so that it can be reused.

Specified by:

reset in class DGCUnmarshalContext

Returns:

true, if an acknowledgement must be sent
