/*********************** 代码块解释 *********************************
*
* 由于开发人员平时会使用单机版本开发，而正式部署时，又会选用 C/S 架构。
* 所以需要保证单机版本和 C/S 架构版本的模式是一样的。也就是说，在单机模式下，
* 在通过门户访问时，模拟网络版，clone 出一个新的对象。
* 这样，在底层 Update 更改 obj 时，不会影响上层的实体。
* 而是以返回值的形式把这个被修改的实体返回给上层。
*
* 20120828
* 但是，当在服务端本地调用时，不需要此模拟功能。
* 这是因为在服务端本地调用时（例如服务端本地调用 RF.Save），
* 在开发体验上，数据层和上层使用的实体应该是同一个，数据层的修改应该能够带回到上层，不需要克隆。
*
