Question

只是想知道取消时间表的最佳方法是什么。

目前我使用链接到调度程序任务的var，并将其取消，如下所示：

private var scheduterLink: akka.actor.Cancellable = null

def receive = {
    case Test => {
       if(...){scheduterLink.cancel}    
}

如果没有 var 链接，如何做更多示例？

谢谢！

如果您更喜欢不可变的解决方案，您可以像这样更改Actor的状态：

  def receive: Receive = withoutCancel

  def withoutCancel:Receive = {
    case x =>
      if(???){
        context.become(withCancel(context.system.scheduler.schedule(....)))
      }
    ???
  }

  def withCancel(cancellable:Cancellable):Receive = {
    case Test =>
      if(???){
        cancellable.cancel()
        context.unbecome()
      }          
     ???
  }

我想你应该试试这个：

ActorRef tickActor = system.actorOf(Props.create(Ticker.class, this));

//This will schedule to send the Tick-message
//to the tickActor after 0ms repeating every 50ms
Cancellable cancellable = system.scheduler().schedule(Duration.Zero(),
Duration.create(50, TimeUnit.MILLISECONDS), tickActor, "Tick",
system.dispatcher(), null);

//This cancels further Ticks to be sent
cancellable.cancel();
