```
public interface ManagedActorClassification
```
Maps ActorRefs to ActorRefs to form an EventBus where ActorRefs can listen to other ActorRefs.
All subscribers will be watched by an org.apache.pekko.event.ActorClassificationUnsubscriber and unsubscribed when they terminate. The unsubscriber actor will not be stopped automatically, and if you want to stop using the bus you should stop it yourself.
