Package akka.cluster.sharding

Class ShardCoordinator.RebalanceWorker

java.lang.Object

akka.cluster.sharding.ShardCoordinator.RebalanceWorker

All Implemented Interfaces:

Actor, ActorLogging, Timers

Enclosing class:

ShardCoordinator

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

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.ShardCoordinator.RebalanceDone to its parent ShardCoordinator. If the process takes longer than the handOffTimeout it also sends akka.cluster.sharding.ShardCoordinator.RebalanceDone.

Method Detail

context

public ActorContext context()

Description copied from interface: Actor

Scala API: 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!

ActorContext is the Scala API. getContext returns a AbstractActor.ActorContext, which is the Java API of the actor context.

Specified by:

context in interface Actor

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

akka$actor$Actor$_setter_$context_$eq

protected void akka$actor$Actor$_setter_$context_$eq(ActorContext x$1)

Description copied from interface: Actor

Scala API: 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!

ActorContext is the Scala API. getContext returns a AbstractActor.ActorContext, which is the Java API of the actor context.

Specified by:

akka$actor$Actor$_setter_$context_$eq in interface Actor

akka$actor$Actor$_setter_$self_$eq

protected final void akka$actor$Actor$_setter_$self_$eq(ActorRef x$1)

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:

akka$actor$Actor$_setter_$self_$eq in interface Actor

remaining

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

public void remaining_$eq(scala.collection.immutable.Set<ActorRef> x$1)

receive

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

Description copied from interface: Actor

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

Specified by:

receive in interface Actor

stoppingShard

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