Hi,
I know that flex does not support multi threading however, I would like to clear a doubt. I have two events that call a same function. Suppose the two events occur at the same instant (or in quick succession) will the handler be called twice, one after the other or there is a chance that if the handler function is taking too much time to execute the same handler can start executing simultaneously.
Thnanks
The handler will be called twice, once with each event. The second call (and essentially, the entire app) will be blocked until the first call has returned.
Here's a nice overview of the event cycle--doesn't specifically address your question, but it's a nice broad picture.
And you can't go wrong with the elastic racetrack.
Yes it will always get called twice. Yes one of the two calls will complete before the other is started. Unless you are doing something like dispatching an event in the handler for another handler to work on, then it all goes out the window! Even then I believe the first call will complete, but the event it dispatched may get resolved before the second call happens, sometimes....sorta. ;) YMMV
If you didn't know, using PixelBender, Flex can do multi-threading. Other than for graphics, you can make use of pixelbender to do mathematical functions quickly which you may find a use for :)
