动态铸造在ActionScript [英] Dynamically Casting In ActionScript

问题描述

有没有办法来动态地投中的Actionscript？我要完成由以下code说明什么：

Is there a way to cast dynamically in Actionscript? What I want to accomplish is illustrated by the following code:

        var Val:*;
        var S:String=SomeTextEdit.text;
        switch (DesiredTypeTextEdit.text) {
          case 'int':Val=int(S);break; 
          case 'uint':Val=uint(S);break; 
          case 'String':Val=String(S);break; 
          case 'Number':Val=Number(S);break; 
          ...
        }
        SomeDisplayObject[SomePropertyNameTextEdit.text]=Val;

我在寻找的东西像下面的伪code：

I am looking for something LIKE the following PSEUDOCODE:

SomeDisplayObject[SomePropertyName]=eval(DesiredType)(SomeTextEdit.text);

是的，我已经认识到的eval是上不了台面的，也不是怎么一会用它。

Yes, I already realize that "eval" is not on the table, nor is that how one would use it.

什么是正确的方法是什么？

What's the RIGHT way?

勾选mapToFlexObjects功能。他基本上是从文本阅读，并在运行时分配类。

Check the "mapToFlexObjects" function. He's basically reading from text and assigning classes at runtime.
