// Groovy pseudo-code
class FizzBuzz {
    ActorSystem actorSystem

    static void main(String[] args) {
        FizzBuzz d = new FizzBuzz()
        d.run()
    }

    void run() {
        Initialize initCmd = new Initialize()
        MasterActor master = actorSystem.get(...)

        // Tells the entire actor system to initialize itself and start doing stuff.
        // ChickenCluckDetector is an actor managed/supervised by MasterActor.
        master.tell(initCmd,...)
    }

    // Called when a ChickenCluckDetector actor inside the actor system receives
    // a 'Cluck' message.
    void onChickenGoesCluck(Cluck cluck) {
        // Do something
    }
}

以下ChickenCluckDetector演员：

class ChickenCluckDetector extends UntypedActor {
    @Override
    void onReceive(Object message) {
        if(message instanceof Cluck) {
            Cluck cluck = message as Cluck

            // Now,how to pass the message safely/properly to FizzBuzz#onCluck?
        }
    }
}

所以手头的问题是如何安全/正确地将Cluck消息传递给FizzBu​​zz#onCluck(Cluck),它存在于actor系统之外？我可以提供一个关于ChickenCluckDetector的FizzBu​​zz引用,如下所示：

class ChickenCluckDetector extends UntypedActor {
    FizzBuzz fizzBuzz

    @Override
    void onReceive(Object message) {
        if(message instanceof Cluck) {
            Cluck cluck = message as Cluck

            fizzBuzz.onCluck(cluck)
        }
    }
}

但我有一种感觉,这违反了Akka的最佳实践,可能导致各种基于并发的问题,特别是如果只有一个FizzBu​​zz(有)非演员/驱动程序,以及一万个ChickenCluckDetector演员.想法？
