I was wondering if there are any plans to consider continuation
support in flash/flex? ...predominantly to support the concept of a
smarter "Thread.sleep(n)" without blocking or disrupting the
single-threaded execution model.
for context, here is a "sleep" pseudo-example using the continuations
concept:
function example {
trace("before");
sleep(2000);
trace("after 2 seconds");
}
function sleep(sleep_millis:int) {
var savepoint:Continuation = Continuations.new(); // creates a
holder that will capture the execution stack state at the next suspend()
setTimeout(function(event:Event):void {
Continuations.resume(savepoint); // resumes the
saved execution stack
},sleep_millis);
Continuations.suspend(savepoint);
}
For my purposes, I am writing a general-purpose tool for developers
that would locate one or more components in the UI hierarchy (by some
criteria), then return those components so they could interact with them.
In searching for said components, I have come across embedded
SWFLoaders which are not yet finished loading/reloading, and sleep()
(via continuations) would allow checking it's state periodically and
not disrupt the execution stack, callers code or block the overall
application.
There are several other cases where this would be useful, but I just
wanted to start a dialog on it.
