public interface BusCreationListener
The listener interface for receiving notification of when
Busobjects are created. It's a simplified form of BusLifeCycleListener that takes the target Bus as a parameter which is appropriate if the listener needs to be a singleton that works with multiple Bus objects. A common pattern would be to register a full BusLifeCycleListener on the target Bus to receive full Bus events
(Bus b)Invoked to create a BusLifeCycleListener.
