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!

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)

akka$actor$Actor$_setter_$context_$eq

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

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

Parameters:

x$1 - (undocumented)

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

Returns:

(undocumented)

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

supervisorStrategy

public OneForOneStrategy 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)

spawnChildWithCapacityProtection

public void spawnChildWithCapacityProtection(SelectionHandler.WorkerForCommand cmd,
                                             int retriesLeft)
