ActorRef
matching this selection.
The result is returned as a Future that is completed with the ActorRef
if such an actor exists. It is completed with failure ActorNotFound
if
no such actor exists or the identification didn't complete within the
supplied timeout
.
Under the hood it talks to the actor to verify its existence and acquire its
ActorRef
.
