public class RpcClientGmsImpl
extends RpcGmsImpl
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.

Method Index

o CreateInstance(RpcGMS)
o HandleJoin(Address)
o HandleLeave(Address)
Returns false.
o HandleMerge(Vector, Vector, long)
Returns immediately.
o HandleSuspect(Address)
Returns immediately.
o HandleUpEvent(Event)
o HandleViewChange(ViewId, Vector)
o Join(Address)
Will generate a CONNECT_OK event.
o Leave(Address)
o Merge(Vector)
o Suspect(Address)

Methods

o CreateInstance 
 public static RpcClientGmsImpl CreateInstance(RpcGMS gms)
o Join 
 public void Join(Address mbr)
Will generate a CONNECT_OK event. Determines the coordinator and sends a unicast Join() message to it. If successful, we wait for a ViewChange (can time out). If view change is received, impl is changed to an instance of RpcParticipantGmsImpl. Otherwise, we continue trying to send Join() messages to the coordinator, until we succeed (or there is no member in the group. In this case, we create our own singleton group).

Parameters:
mbr - Our own address (assigned through SET_LOCAL_ADDRESS)
