  2. final case class Publish[E](event: E) extends Command with Product with Serializable

    Publish an event of type E by sending this command to the akka.actor.typed.ActorSystem.eventStream.

  3. 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 or subtypes of E by sending this command to the akka.actor.typed.ActorSystem.eventStream.

    Subscribe a typed actor to listen for types or subtypes of E by sending this command to the akka.actor.typed.ActorSystem.eventStream.

    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)
  4. final case class Unsubscribe[E](subscriber: ActorRef[E]) extends Command with Product with Serializable

    Unsubscribe an actor ref from the event stream by sending this command to the akka.actor.typed.ActorSystem.eventStream.
