A Singleton that Flex Developers must know about

Normal.dotm 0 0 1 138 789 Farata 6 1 968 12.0 0 false 18 pt 18 pt 0 0 false false false Don “t create new singletons ndash; just use what you already have.

Each real-world software developer knows at least one design pattern ndash; Singleton. Flex has some specifics in implementing Singletons due to lack of private constructors in ActionScript, but the goal of this little writeup is not to show you how to implement Singleton, but rather to discourage you from doing this because each Flex application already has a singleton ndash; just use it.

I “ve recorded an eight-minute video that will shows how you can use the Application object as your one and only singleton when needed. See if you can answer the question that I asked at the end of the video.

This is one of many tricks and techniques that consultants from Farata Systems use while working on enterprise Flex projects, and we “ll continue to share them with you in the form of such mini demos as well as in one of our public seminars like the one on August 7 in New York City or on September 24-25 in London, UK.
