abstract class ActorRef[-T] extends Comparable[ActorRef[Nothing]]
An ActorRef is the identity or address of an Actor instance. It is valid only during the Actor’s lifetime and allows messages to be sent to that Actor instance. Sending a message to an Actor that has terminated before receiving the message will lead to that message being discarded; such messages are delivered to the akka.actor.DeadLetter channel of the akka.event.EventStream on a best effort basis (i.e. this delivery is not reliable).
