SINGLETON CLASS

In object-oriented programming , a singleton class is a class that can have only one object (an instance of the class) at a time. It's good when you only want one object across the whole of your application It is usually used in flex to add Global State to a project.In other words, It allows you to do things like set and have access to global variables from anywhere in your application.

To access a variable from the Singleton class we use the following.

private var model:Singleton = Singleton.getInstance();

Full code goes here!

<pre>public class Singleton
            {

                    private static var instance:Singleton = new Singleton();

                    public var flexData:String = "FirstApp";
                    public var userScore:int = 0;

                       public function Singleton()
                {
                    if(instance)
                    {
        throw new Error ("new instance cannot be created");
                   }
                }

                public static function getInstance():Singleton
                {
                    return instance;
                }
            }

Hope this will help you!!!
