That’d only be the case in completely synchronous execution. And the behaviours body would actually execute on that line — but it doesn’t. Here once you returned a new behaviour, control is given back to whoever is invoking things (in great simplification, “the actor system”).

Consider for instance the following behavior definition given in the documentation: private def chatRoom(sessions: List[ActorRef[SessionEvent]]): Behavior[Command] = Actor.immutable[Command] { (ctx, msg) ⇒ msg match { case GetSession(screenName, client) ⇒ val wrapper = ctx.spawnAdapter { p: PostMessage ⇒ PostSessionMessage(screenName, p.message) } client ! SessionGranted(wrapper) chatRoom(client :: sessions) case PostSessionMessage(screenName, message) ⇒ val mp = MessagePosted(screenName, message) sessions foreach (_ ! mp) Actor.same } } The chatRoom function is not tail-recursive, therefore each time the behavior receives a message it will create a new frame, right? -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
