这个类是怎么生成的

JAVA动态生成类在java的加载过程一般都是要预先定义java类，然后通过经过加载->连接->初始化三步。连接过程又可分为三步：验证->准备->解析。但是在日常的工作中有时候需要动态生成类，那第这种情况怎么办呢？我是根据传入的Demo.java中的属性生成新类。新类的属性是Demo类属性的值。// 动态添加字段和getter/setter。// 继承DynamicEntity。// 转换为Class对象并返回。1、先定义一个空的类，仅作为动态生类的父类标识。// 生成getter。// 生成setter。阅读详情

我来看别人的项目，看到一个类CMSComm，看不除是怎么添加的：因为看上去不像从MFC CLASS的，也像是Generic CLASS类的；也不像是Form class类型的！这个类的头文件里面居然没有构造函数和析构函数；为什么啊？从那生成的啊？？？
我把头文件复制下来了：
