Count handlers

[melug]

I am looking for a way to count number of subscribers for a specific event. The methods of Bus class have private fields and methods that its child class can't access. Because, my interest is "if anyone have received event?", currently I can't answer question, or is there a way to work around?

If an event is posted, and there are no subscribers to receive it, a DeadEvent will be posted that contains the event itself, and the object that created it.

Yes, DeadEvent is the proper way to do this. If you need to know about the number of subscribers or who the subscribers are then an event bus is likely not the right pattern.
