Actor is a very simple base class—just a dependency on the eventDispatcher (a property of Actor) that is shared throughout the application. This allows your models and services to dispatch state and status updates that the whole application can pick up.

It is important to understand that you do not need to extend Actor. Actor is provided for your convenience, to give you the core functionality that is commonly needed by models and services in a Robotlegs application. If your models and services don’t need that core functionality, or you would like them to be reused in a non-Robotlegs code base, you can provide the functionality of Actor manually without extending anything.
