public class ClientGmsImpl
extends GmsImpl

Client part of GMS. Whenever a new member wants to join a group, it starts in the CLIENT role. No multicasts to the group will be received and processed until the member has been joined and turned into a SERVER (either coordinator or participant, mostly just participant). This class only implements Join (called by clients who want to join a certain group, and ViewChange which is called by the coordinator that was contacted by this client, to tell the client what its initial membership is.
