    This object contains elements which make writing actors and related code more concise, e.g. when trying out actors in the REPL.

    For the communication of non-actor code with actors, you may use anonymous actors tailored to this job:

    import ActorDSL._
    import scala.concurrent.util.duration._
    
    implicit val system: ActorSystem = ...
    
    implicit val i = inbox()
    someActor ! someMsg // replies will go to `i`
    
    val reply = i.receive()
    val transformedReply = i.select(5 seconds) {
      case x: Int => 2 * x
    }

    The receive and select methods are synchronous, i.e. they block the calling thread until an answer from the actor is received or the timeout expires. The default timeout is taken from configuration item akka.actor.dsl.default-timeout.

    When defining actors in the REPL, say, you may want to have a look at the Act trait:

    import ActorDSL._
    
    val system: ActorSystem = ...
    
    val a = actor(system, "fred")(new Act {
        val b = actor("barney")(new Act {
            ...
          })
    
        become {
          case msg => ...
        }
      })

    Note that actor can be used with an implicit akka.actor.ActorRefFactory as shown with "barney" (where the akka.actor.ActorContext serves this purpose), but since nested declarations share the same lexical context "fred"’s ActorContext would be ambiguous if the akka.actor.ActorSystem were declared implicit (this could also be circumvented by shadowing the name system within "fred").

    Note: If you want to use an Act with Stash, you should use the ActWithStash trait in order to have the actor get the necessary deque-based mailbox setting.
