用一些动作装饰演员

Question

我读到了危险案例there。

现在，我正在开发一个应该跟踪传入消息的扩展。即当消息到达时，我必须通知某个外部系统该消息已到达。

在另一个actor中创建actor对象并将其传递给props工厂是否安全？

class HandlingActorWrapper(val decoratee: Actor) extends Actor {

    override def receive: Receive = {
       System.out.println("Message recieved");
       decoratee.receive
    }
}

object HandlingActorWrapper{
    def props(actor: Actor) = Props(new HandlingActorWrapper(actor))
}

class MyActor extends Actor {
    override def receive: Receive = {
       //handling messages
    }
}

class SomeActor extends Actor {
   var child : ActorRef = _

   override def preStart() = {
                                                                    //>>|HERE
      child = context.system.actorOf(HandlingActorWrapper.props(new MyActor))
   }
   //other
}
