Exactly, without reading your post I came to the same solution. And it is
very elegant. I have now the following setup:
View.Button -> Click
View.clickHandler ->
message.sender = view
message.name = message
message.data = additional data
post message to eventbus
Controller
subscribes to eventbus with
message = message and
handler = messageHandler
So, now neither the view or the controller need any references to each other
== loose coupling == good!.
In the controller, when I receive the message I also want to check the
sender, using an interface, whether it is the right sender. So, then I am
guaranteed that I can use that sender.
What's even better, now I can use the same controller for different views,
as long as they implement the interface.
I know there is an assertInterface method. But is there also an
'hasInterface' that returns a boolean?
