Class ShardCoordinator.RebalanceWorker

java.lang.Object

akka.cluster.sharding.ShardCoordinator.RebalanceWorker

All Implemented Interfaces:

Actor

Enclosing class:

ShardCoordinator

public static class ShardCoordinator.RebalanceWorker
extends java.lang.Object
implements Actor

INTERNAL API. Rebalancing process is performed by this actor. It sends BeginHandOff to all ShardRegion actors followed by HandOff to the ShardRegion responsible for the shard. When the handoff is completed it sends akka.cluster.sharding.RebalanceDone to its parent ShardCoordinator. If the process takes longer than the handOffTimeout it also sends akka.cluster.sharding.RebalanceDone.

Method Detail

context

public ActorContext context()

Description copied from interface: Actor

Stores the context for this actor, including self, and sender. It is implicit to support operations such as forward.

WARNING: Only valid within the Actor itself, so do not close over it and publish it to other threads!

(undocumented)

self

public final ActorRef self()

Description copied from interface: Actor

The 'self' field holds the ActorRef for this actor.

Can be used to send messages to itself:

 self ! message
 

Specified by:

self in interface Actor

Returns:

(undocumented)

remaining

public scala.collection.immutable.Set<ActorRef> remaining()

receive

public scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> receive()

Description copied from interface: Actor

This defines the initial actor behavior, it must return a partial function with the actor logic.

Specified by:

receive in interface Actor

Returns:

(undocumented)

stoppingShard

public scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> stoppingShard()

done

public void done(boolean ok)
