Roger Schildmeijer updated DEFT-195:
------------------------------------
Description:
Inspired by twisteds Deferreds
(http://twistedmatrix.com/documents/current/core/howto/defer.html).
Deferreds represents the result of an asynchronous operations. (At first they
look very similar to java.util.concurrent.Future, but they differ somewhat).
You can..
attach callbacks and errbacks to a Deferred.
chain callbacks
take care of error handling in a more "deterministic" way
Drawbacks:
complex abstraction (doesn't fit that well into the current simple architecture)
had to add a return type to AsyncResult
"type safety" issues (hint: return type of AsyncResult.[onSuccess, onFailure])
