Easy way to listen context dispatch

[hbakhtiyor]

override public function listEventInterests():Array
{
  return [FileEvent.DOWNLOADING, FileEvent.UPLOADING];
}

override public function handleEvent(event:Event):void
{
  switch(event.type)
  {
    case FileEvent.DOWNLOADING:
      // do something
      break;
    case FileEvent.UPLOADING:
      // do something
      break;
  }
}

Instead of

override public function initialize():void
{
  addContextListener(FileEvent.DOWNLOADING, _onFile_DownloadingHandler);
  addContextListener(FileEvent.UPLOADING, _onFile_UploadingHandler);
  // a lots of addContextListener 
}

Same as PureMVC event instead notification. It's just idea without unit testing. What do you think?

There's a number of problems with this approach:

1. it creates monolithic handleEvents methods if you have lots of events.
2. it allows for orphaned events: the event is still registered for listening, but nothing happens with it in the event handler.
3. it can't differentiate between two different events with the same type
4. there's asymmetry with how you listen to context events and how you listen to view events.

So no, I'm sorry, we won't consider this. And I don't quite understand how this is easier? There's a lot more boilerplate code to be written.

Agree! I'm in PureMVC habit :laughing: Thanks

No probs! If you're new to RL you'll notice a lot of things are quite similar to PureMVC, but the main idea was to try and reduce a lot of the boilerplate code necessary to get PMVC up and running. It takes a little while to adjust.

Hi @hbakhtiyor, thanks for all the pull requests and suggestions! It's great that you're getting involved. As @creynders pointed out, there might be quite a lot that we don't use or pull in, but it's still great to have these ideas to discuss.
