Class PresenceThread

java.lang.Object
  java.lang.Thread
      muskel.PresenceThread

All Implemented Interfaces:

java.lang.Runnable

public class PresenceThread
extends java.lang.Thread

This is the thread run by the RMI RemoteWorker server to answer the request for presence issued by other StandardEval components.
It listens to a Multicast group and answers with the name of the machine where it is running. The asking thread can therefore manage a new worker at that machine.
