Hi,
If you dont like the as3 event mechanism, you can write your own, but
looking at your code, there are a number of things I wouldn't do:
- setting local variables on the activation stack, it leads to memory waste
- executing the asynchronoustask before setting the callback handlers
- prepending everything with m
- using simple strings as type instead of static public event types
- using the callback mechanism (overriding the onTasketc method) combined
with the event types and required params
So to be honest I wouldnt port this way of working to AS3 , I'd take it as
an opportunity to do it better this time around. We're not on monkey island
you know;-)
