public class ParticipantManager
extends Observable
implements Marshallable
The ParticipantManager keeps a list of all of the participants in a particular session. When one is added or removed it notifies all of the session's routers, which can choose to keep their own routing lists or to query this object each time they route. Each client is identified by its own unique string, which serves as the key into the Hashtable where the clients are kept.

Returns:

o notifyObservers 
 public synchronized void notifyObservers(Object arg)
For some reason the default implementation requires that a flag be set before observers get notified. I couldn't figure out why, so this sets the flag and then calls the default implementation.

o clear 
 public void clear()
Returns:
clears the participants, nulls the session
