final case class Subscribe[E](subscriber: ActorRef[E])(implicit classTag: ClassTag[E]) extends Command with Product with Serializable

Subscribe a typed actor to listen for types and subtypes of E by sending this command to the akka.actor.typed.ActorSystem.eventStream. The same actor can create multiple subscriptions for different types.

Simple example

sealed trait A
case object A1 extends A
//listen for all As
def subscribe(actorSystem: ActorSystem[_], actorRef: ActorRef[A]) =
  actorSystem.eventStream ! EventStream.Subscribe(actorRef)
//listen for A1s only
def subscribe(actorSystem: ActorSystem[_], actorRef: ActorRef[A]) =
  actorSystem.eventStream ! EventStream.Subscribe[A1](actorRef)
