Method Detail

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

clearState

public void clearState()

cluster

public Cluster cluster()

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

emptyMembershipState

public MembershipState emptyMembershipState()

eventStream

public EventStream eventStream()

membershipState

public MembershipState membershipState()

membershipState_$eq

public void membershipState_$eq(MembershipState x$1)

postStop

public void postStop()

Description copied from interface: Actor

User overridable callback.

Is called asynchronously after 'actor.stop()' is invoked. Empty default implementation.

Specified by:

postStop in interface Actor

preRestart

public void preRestart(java.lang.Throwable reason,
                       scala.Option<java.lang.Object> message)

Description copied from interface: Actor

Scala API: User overridable callback: '''By default it disposes of all children and then calls postStop().'''

Specified by:

preRestart in interface Actor

Parameters:

reason - the Throwable that caused the restart to happen

message - optionally the current message the actor processed when failing, if applicable

Is called on a crashed Actor right BEFORE it is restarted to allow clean up of resources before Actor is terminated.

receive

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