All Implemented Interfaces:

com.lbf.commons.messaging.IMessageHandler

public class CLB_Terminator
extends LRCMessageHandler

This handler processes messages of type EXT_TerminateLRC. This message indicates a remote termination of the federates involvement in the federation. Thus, it will make all appropriate changes to the LRC as if it had resigned itself.

As a result of this termination, federates should receive a "not joined" exception when attempt to call any method on the RTIambassador.

*** NOTE *** There is a potential race condition here as a federate initiated request could be halfway through processing in another thread. Given that the process of these messages are going to be out-of-the-norm style events, I've decided not to impose on the request sink the burden of synchronization simply to keep everything happen in the unlikely event that extension messages will ever be processed. Even when they are, it is reasonable to expect that something like the remote termination of a federate might prompt exceptions on the client side.
