Concrete Value Members

  1. implicit val context: ActorContext

    Scala API: Stores the context for this actor, including self, and sender.

    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!

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

    Actor
  2. def getContext(): AbstractActor.ActorContext

    Returns this AbstractActor's ActorContext The ActorContext is not thread safe so do not expose it outside of the AbstractActor.

  4. def getSender(): ActorRef

    The reference sender Actor of the currently processed message.

    The reference sender Actor of the currently processed message. This is always a legal destination to send to, even if there is no logical recipient for the reply, in which case it will be sent to the dead letter mailbox.
