Package akka.remote.testconductor

Class BarrierCoordinator

java.lang.Object

akka.remote.testconductor.BarrierCoordinator

All Implemented Interfaces:

Actor, ActorLogging, FSM<BarrierCoordinator.State,BarrierCoordinator.Data>, LoggingFSM<BarrierCoordinator.State,BarrierCoordinator.Data>, Listeners

public class BarrierCoordinator
extends java.lang.Object
implements Actor, LoggingFSM<BarrierCoordinator.State,BarrierCoordinator.Data>

This barrier coordinator gets informed of players connecting (NodeInfo), players being deliberately removed (RemoveClient) or failing (ClientDisconnected) by the controller. It also receives EnterBarrier requests, where upon the first one received the name of the current barrier is set and all other known clients are expected to join the barrier, whereupon all of the will be sent the successful EnterBarrier return message. In case of planned removals, this may just happen earlier, in case of failures the current barrier (and all subsequent ones) will be failed by sending BarrierFailed responses.

User overridable callback: By default it calls preStart().

Specified by:

postRestart in interface Actor

Parameters:

reason - the Throwable that caused the restart to happen
