Akka java - Synchronized Children Actor


我刚开始使用 Akka(在 Java),我遇到了一个不知道如何解决的问题。

我有N个玩家和一个神谕。 创建后,所有玩家必须与神谕沟通,神谕必须回应"winner / loser"。

问题是我不知道如何依次、整齐地、一次一个地传达玩家的策略:
例如:玩家 1 -> 玩家 2 -> 玩家 3 -> 玩家 1 -> 玩家 2 -> ...

玩家class:

public class MyPlayers extends UntypedActor {

/*
* I created one context of N Player
*/
public MyPlayers() { }

public void preStart() {
    //in this way all N players at the beginning, start to communicate concurrently.
    ActorSelection oracle = getContext().actorSelection("//Main/user/app/oracle"); 
    oracle.tell(new MyMessage(myValue), getSelf());
}

@Override
public void onReceive(Object msg) throws Exception {

    if (msg instanceof MyMessage) {
        //do something
        sender().tell(MyMessage, getSelf());

    }


    if (msg instanceof DoneMsg) {
        if (((DoneMsg) msg).isDone()) {
            log("Stop Players");
            getContext().stop(getSelf());
        }
    }

}

甲骨文class:

public class Oracle extends UntypedActor {
private int nPlayers;
public Oracle(int nPlayers) {
    this.nPlayers = nPlayers;
}

public void preStart() {
    stateGame = false;  //When the play starter, there is not any wins.
}

@Override
public void onReceive(Object msg) throws Exception {

    if (msg instanceof MyMessage) {
        if (!stateGame) {
            //do something
            sender().tell(MyMessage, getSelf());
        }
        else {
            //do something
            getContext().stop(getSelf());
        }
    }
}

通过排除竞争来有序地与玩家沟通的最佳策略是什么?

感谢大家。

有序地向参与者发送消息的两个基本选项:
1. 玩家作为routies的循环路由器
2. 持有对玩家的引用并遍历他们的数组或集合

不相关的注释:
避免演员选择。通过 constructor/props 或消息将 oracle 引用传递给玩家。选择很少是合理的(主要是为了远程处理),这是一种危险的做法。
