EventStream

class EventStream extends LoggingBus with SubchannelClassification

An Akka EventStream is a pub-sub stream of events both system and user generated, where subscribers are ActorRefs and the channels are Classes and Events are any java.lang.Object. EventStreams employ SubchannelClassification, which means that if you listen to a Class, you'll receive any message that is of that type or a subtype.

The debug flag in the constructor toggles if operations on this EventStream should also be published as Debug-Events
