Constructor Detail

TypedActor

public TypedActor(java.util.concurrent.atomic.AtomicReference<R> proxyVar,
                  scala.Function0<T> createInstance,
                  scala.collection.immutable.Seq<java.lang.Class<?>> interfaces)

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!

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

Specified by:

context in interface Actor

Returns:

(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)

proxyVar

public java.util.concurrent.atomic.AtomicReference<R> proxyVar()

supervisorStrategy

public SupervisorStrategy supervisorStrategy()

Description copied from interface: Actor

User overridable definition the strategy to use for supervising child actors.

Specified by:

supervisorStrategy in interface Actor

Returns:

(undocumented)

preStart

public void preStart()

Description copied from interface: Actor

User overridable callback.

Is called when an Actor is started. Actors are automatically started asynchronously when created. Empty default implementation.

Specified by:

preStart in interface Actor

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

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.

postRestart

public void postRestart(java.lang.Throwable reason)

Description copied from interface: Actor

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

Specified by:

postRestart in interface Actor

Parameters:

reason - the Throwable that caused the restart to happen

Is called right AFTER restart on the newly created Actor to allow reinitialization after an Actor crash.

withContext

protected <U> U withContext(scala.Function0<U> unitOfWork)

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)
