Get the mediator instance for a given view instance or class

Hi,

The current MediatorMap implementation is not exposing the MediatorFactory. Is there a specific reason why we can't access the API? Specifically I need some way of accessing mediator instances.

Thanks,
Matan

   Hi Matan,

   Sorry for the delay - I've been a little under the weather. I'll take a look and get back to you asap.

   Yup. The MediatorFactory is a private class - to keep the library maintainable going forward we have to reduce the API footprint that we officially support. The MediatorFactory and MediatorManager classes are internal implementation details that may be wildly changed or even completely dropped in the future.

   I think we need to find a solution to your actual need (getting the list of mediators for a given view) without exposing framework internals.

   As a matter of interest, what is your use case for this requirement?

   Hi Shaun,

   Sorry to hear you're feeling under the weather, hope you feel better soon. :)

   EDIT: Ok, you've opened the ticket, below is my reasoning anyway. :)

   I've written a RL2 extension called StateMap which piggy backs off the MediatorMap. The resulting api looks like this:

   stateMap.map(MainScreen).toMediator(MainScreenMediator).withStates(SecId.MAIN_SCREEN);

   I'm using AS3Navigator as my internal state handler. In order to map the state, I need to provide an instance of a "INavigationResponder". Which in this case will always be a Mediator instance.

   Luckily I've got a work-a-round by using my custom implementation of StarlingMediatorMap which simply exposes the factory.

   The resulting "dirty" code with my StateMapping looks like this:
   

   public function get responder() : INavigationResponder
   {
       return INavigationResponder(StarlingMediatorMap(_mediatorMap).factory.getMediator(view, IMediatorMapping(_mediatorConfigurator)));
   }
   

   Thanks,
   Matan
