      • 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!

        Returns:
        (undocumented)

        self in interface Actor
        Returns:
        (undocumented)
