AS中CLibInit的作用是什么 ？

今天在破解一个 播放器的时候，破解的as代码中有这样的代码 ：
this._cloader = new CLibInit();
this._lib = this._cloader.init();
var _loc_2:* = Base64.decodeToByteArray(param1)
this._lib.getSize(_loc_2, _loc_2.length);

这里 的最后的getsize方法相当于js或者java的什么方法 ，CLibInit这个加密算法的具体步骤是什么样的呢？

package cmodule.ccYouku

    import flash.display.*;
    import flash.utils.*;

    public class CLibInit extends Object
    {

            return;

呵呵，这个是Alchemy，查找下，应该是c++写的代码，使用e:Alchemy技术给flash使用的方法。
