      • ask

        public <U> scala.concurrent.Future<U> ask​(scala.Function1<ActorRef<U>,​M> message,
                                                  Timeout timeout)
        Description copied from interface: EntityRef
        Allows to "ask" the EntityRef for a reply. See AskPattern for a complete write-up of this pattern

        Note that if you are inside of an actor you should prefer akka.actor.typed.scaladsl.ActorContext.ask as that provides better safety.

        Example usage:

        
         case class Request(msg: String, replyTo: ActorRef[Reply])
         case class Reply(msg: String)
        
         implicit val timeout = Timeout(3.seconds)
         val target: EntityRef[Request] = ...
         val f: Future[Reply] = target.ask(Request("hello", _))
         

        Please note that an implicit Timeout must be available to use this pattern.
