ActionScript 3.0 :: Static Class Can't Replace Singleton Design Pattern
Jan 1, 2010I am not able to understand, why a static class cannot replace a Singleton design pattern .
Cannot a static class, can be used to ensure, the class is never/once only, instantiated. Because that is the facility "static" key words provide , however it doesnot allow instantiation, but that is much similar to the limitation of instantiation once only.

ActionScript 3.0 :: Using Singleton In A Sub-class?
Oct 30, 2009In the Singleton design pattern you can throw a runtime error if the instance has already been created. But this doesn't work when your singleton class extends another class and has to call super() in its constructor, because (for some reason) you cannot call super() if you've already called throw(), or in fact, you cannot compile code that has a potential call to throw() (for example, in an IF statement) that comes BEFORE that call to super().

Mar 21, 2011I have created a Network class singleton to represent our xml calls. The purpose of the class is to load in various xml calls and then load into a 2 dimensional array.The 2 main variables that I want to release are "mChannels" and "epgXML". When I call the function term(), the memory never gets released. I am initializing this Network class once (mNetwork = Network.init(), and then referencing the singleton through the getInstance function. I call the term() function but the memory never goes down. What am I doing wrong with garbage collection?[code]

Actionscript 3 :: Unit Testing With A Singleton Using Inversion Of Control
Jan 26, 2011I am developing an AS3 application which uses a Singleton class to store Metrics in Arrays. It's a Singleton because I only ever want one instance of this class to be created and it needs to be created from any part of the app. The difficulty comes when I want to unit test this class. I thought adding public getters and setters would enable me to unit test this properly and would be useful for my app. I have read that changing to a Factory pattern will enable unit testing or using Inversion of control. This would of course make it more flexible too. I would like to know of people's thoughts on this matter as there are SO many conflicting opinions on this!
