[Flashcoders] Dynamic runtime class', another example.
I've just done some experimenting with dynamic runtime class'. I think what i've come up with might be interesting to others who are experimenting in this area. One thing that i think is different from other methods that i've seen, is the use of Deferreds [1][2], allowing for asynchronous calls to class' that are not yet loaded, but from which you want to get back the results of your call. Also the ability to set wether you want a method to be asynchronous or not (via naming magic - ie. add '_deferred' to any method call (mymethod_deferred), and you make that method asynchronous). The code is not 100% stable good to go into the enterprise or anything, but i hope that it is an example of (yet another) way to handle runtime dynamic class'. You can see my (long) post here: http://www.theorganization.net/mt/archives/2005/11/29/flash_dynamic_runtime_class.html tinurl: http://tinyurl.com/96usc Check the second update, that's where i have instructions for making the demo work. Or read the whole rambling thing!

Re: [Flashcoders] Dynamic runtime class', another example.
Hi, first off: cool ;). Question though, since flash idea of multithreading is that there are no real threads for us to create and each method runs synchronized (as in public synchronized as in java), what would be a case where i would wanna use asynchronous callbacks? They are used here to support the following case: You wrap a dynamic class. It takes time for that class to load, but you want to call some methods on that class right away, before its loaded. By registering callbacks, you can call a method on the class, and be calledback when the data is ready. So, in this way, you don't have to worry about waiting for the class to load, you just tell it to do something, and it will tell you when it is done. In the example code that i include in the post, you can see that i've called the 'output' method of the wrapper instance, and its running it before the class is loaded. Via callbacks, once the class is loaded, i get the results of calling those methods. I know that the XML object does this, but i think this object since its natively implemented and stuff really does run in a separate thread. Please note that i'm not talking about threads. Perhaps i should have described it as 'queuing' your function calls.
