In my recent work related to events and signals, I had a little discussion about errors that are thrown during the dispatch of an event or signal. I did some investigating to see how EventDispatcher handles this and found something rather surprising.

Introducing TurboSignals
Feb 16
My last article on Callback Strategies highlighted some pretty severe performance differences between my Runnable strategy, as3signals by Robert Penner, and Flash’s native Event system. My simple Runnable technique had an artificial advantage though: it was not a proper library but instead a little bit of code built right into the test app. Today I’m introducing TurboSignals as an AS3 library making use of the Runnable technique.
Callback Strategies

I’ve previously covered ways of implementing in my article on Runnables (aka observers) which showed how to call back about 15 times faster than just using a Function object. There are still more ways to call back though and I didn’t cover them at the time. Today I’ll be adding to Function and Runnables by testing Event and the as3signals library by Robert Penner.
Removing Event Listeners
Jul 1
Making sure you remove event listeners is good for both correctness and garbage collection. Sometimes you don’t want (or need) to hear events any more and some times you just need to release references to aid the garbage collector in memory cleanup. Whatever your reason, there are a few ways to do it.
