【AS3代码】抽象类简单运用

抽象类

package
{
    import flash.display.Sprite;
    public class initialize extends Sprite
    {
        public function initializes():void
        {
            createField();
            createTeam("red");
            createTeam("blue");
            startGame();
        }
        public function createField():void
        {
            //throw new Error("抽象方法!");
        }
        public function createTeam(name:String):void
        {
            //throw new Error("抽象方法!");
        }
        public function startGame():void
        {
            //throw new Error("抽象方法!");
        }
    }
}

 继承抽象类：

package
{
    public class FootballGame extends initialize
    {
        public function FootballGame()
        {
        }
        
        public override function createField():void
        {
            trace("创建足球!");
        }
        public override function createTeam(name:String):void
        {
            trace("创建足球队，名字：" + name);
        }
        public override function startGame():void
        {
            trace("开始足球游戏");
        }
    }
}

 文档类：

package
{
    import flash.display.Sprite;

    public class FactoryExample extends Sprite
    {
        public function FactoryExample()
        {
            var game:FootballGame = new FootballGame();
            game.initializes();
        }
    }
}
