[英]How to create multiple Actors in AKKA by a loop in java?
this is just a learning example, I wan't to create and assign a actor for each element in an array,这只是一个学习示例,我不想为数组中的每个元素创建和分配一个演员,
ActorSystem system = ActorSystem.create("mySystem");
for(String name:namesArray){
ActorRef myActor = system.actorOf(Props.create(Actor.class),name);
}
Will this create multiple actor or will it create actor paths that reference to the same actor?这会创建多个演员还是会创建引用同一演员的演员路径? if its the latter how do i create multiple actors and assign them a identifier?
如果是后者,我如何创建多个参与者并为他们分配一个标识符?
That code will:该代码将:
ActorSystem
ActorSystem
namesArray
(it will throw an InvalidActorNameException
if a name appears a second time in the array)namesArray
中的每个名字创建一个 actor(如果一个名字在数组中第二次出现,它将抛出InvalidActorNameException
) Note that this code as written promptly forgets the ActorRef
for every one of the created actors, meaning that you would not be able to send it a message except by using ActorSelection
which is generally not recommended.请注意,编写的这段代码会立即忘记每个创建的 Actor 的
ActorRef
,这意味着您将无法向它发送消息,除非使用通常不推荐的ActorSelection
。 Going along with this, it's worth noting that the actor will continue running even if there are no ActorRef
s for that actor (actors must be explicitly stopped).与此同时,值得注意的是,即使该演员没有
ActorRef
(必须明确停止演员),该演员仍将继续运行。
