actionscript-3 - 记录调度自定义事件(在 actionscript 3 中)

Question

假设我的 X 类能够调度 3 种类型的(自定义)事件。
在我的类文件中，我应该在哪里以及如何最好地记录这种行为？

Answer 1

添加 [Event]您的类(class)上方的元标记。

来自 Starling Framework 的示例:

package starling.core
{

    /** Dispatched when a new render context is created. */
    [Event(name="context3DCreate", type="starling.events.Event")]

    /** Dispatched when the root class has been created. */
    [Event(name="rootCreated", type="starling.events.Event")]

    /** The Starling class represents the core of the Starling framework.
     *
     *  <p>The Starling framework makes it possible to create 2D applications and games that make
     *  use of the Stage3D architecture introduced in Flash Player 11. It implements a display tree
     *  system that is very similar to that of conventional Flash, while leveraging modern GPUs
     *  to speed up rendering.</p>
     *  
     *  <p>The Starling class represents the link between the conventional Flash display tree and
     *  the Starling display tree. To create a Starling-powered application, you have to create
     *  an instance of the Starling class:</p>
     *  
     *  <pre>var starling:Starling = new Starling(Game, stage);</pre>
     *  
     */ 
    public class Starling extends EventDispatcher
    {
        /** The version of the Starling framework. */
        public static const VERSION:String = "1.2";
