使用接口在向量中传递两种不同类型的数据

In Actionscript3, as the title says, I'm trying to pass two different types of data in one vector through creating an interface for it. Does anybody have an example to do so?

在Actionscript3中,正如标题所说,我试图通过为它创建一个接口,在一个向量中传递两种不同类型的数据。有没有人有这样做的例子?

If they are unrelated objects, you might consider an Array instead. If you want the features of a Vector, then you just treat it like usual: create a Vector with the interface as the type instead of the most common base class.

如果它们是不相关的对象,则可以考虑使用数组。如果你想要Vector的功能,那么你就像平时那样对待它:创建一个以接口为类型而不是最常见的基类的Vector。

    var v:Vector.<IFace> = new Vector.<IFace>();

...and of course implement IFace on those classes you want to put into the Vector

......当然,在你想要放入Vector的类中实现IFace

UPDATE - OK, as an extension of the answer, here's an actual interface...

更新 - 好的,作为答案的扩展,这是一个实际的界面......

    public interface IFace
    {
        function doSomethingAllImplementersCanDo() : Boolean;
    }

...that would go in a file called IFace.as. A class that implements IFace might look like this...

...这将放在一个名为IFace.as的文件中。实现IFace的类可能看起来像这样......

    public class MonsterTruck implements IFace
    {
        public function doSomethingAllImplementersCanDo() : Boolean
        {
            return true;
        }
    }

...and somewhere else in your program...

......以及你程序中的其他地方......

        var v:Vector.<IFace> = new Vector.<IFace>();
        var mt:MonsterTruck = new MonsterTruck();
        v.push( mt );
        var throughIFace:IFace = v.pop();
        trace( throughIFace.doSomethingAllImplementersCanDo() );
