ActionScript 3的自省 - 函数名 [英] Actionscript 3 introspection -- function names

问题描述

我想遍历每个对象的成员。对于每一个成员，我检查，看它是否是一个函数或没有。如果它是一个功能，我想获得它的名字，并执行基于函数的名称一些逻辑。我不知道这甚至有可能，但。是吗？任何提示？

I am trying to iterate through each of the members of an object. For each member, I check to see if it is a function or not. If it is a function, I want to get the name of it and perform some logic based on the name of the function. I don't know if this is even possible though. Is it? Any tips?

例如：

var mems: Object = getMemberNames(obj, true);

for each(mem: Object in members) {
    if(!(mem is Function))
        continue;

    var func: Function = Function(mem);

    //I want something like this:
    if(func.getName().startsWith("xxxx")) {
        func.call(...);
    }

}

我有一个很难找到多少就做这个。感谢您的帮助。

I'm having a hard time finding much on doing this. Thanks for the help.

推荐答案

您伪code是接近做你想要什么。而不是使用getMemberNames，但是，它可以得到私有方法，你可以遍历一个简单的for..in循环的成员，并获得使用括号中的成员的值。例如：

Your pseudocode is close to doing what you want. Instead of using getMemberNames, however, which can get private methods, you can loop over the members with a simple for..in loop, and get the values of the members using brackets. For example:

public function callxxxxMethods(o:Object):void
{
  for(var name:String in o)
  {
    if(!(o[name] is Function))
      continue;
    if(name.startsWith("xxxx"))
    {
      o[name].call(...);
    }
  }
}
