In the code below, remoteListeners is a list of actor string path in remote
Actor Systems.
I use actorFor to get the ActorRef.
val listenersActorRefs = remoteListeners.map(path =>
context.actorFor(path)).toList
val router = context.actorOf(Props.empty.withRouter(BroadcastRouter(routees
= listenersActorRefs)), "remoteListeners")
Suppose the remote actors are not running when the above code is executed,
and later, the remote actors are alive, then
the router will automatically connect to the remote actors.
As actorFor is deprecated, I try replacing actorFor with actorSelection and
use the following to get ActorRef
def getActorRef(path:String, context:ActorContext):ActorRef={
implicit val timeout = Timeout(3, TimeUnit.SECONDS);
val future = context.actorSelection(path).resolveOne().mapTo[ActorRef]
val futureTimeout = Duration(3, TimeUnit.SECONDS);
val actorRef = Await.result(future, futureTimeout)
actorRef
}
The above works if all the remote actors are alive at the beginning. If
remote actors are not alive at the beginning, I do not get the automatic
connect
behaviour when the remote actors are alive.
Is there a way to use actorSelection with the "lazy connect" behaviour ?
Thanks in advance for your assistance !
