由于几乎没有详细阐述BREW接口实现机制方

面的文档，妨害了对BREW接口机制的学习。所以结合自

己的心得体会写了该文档。该文档完整分析了brew中两

种接口实现方式（Aeeinterface和Qinterface），分析

了接口究竟是什么？创建接口时究竟发生了什么？使用

所谓的接口函数（因为其实是宏）时究竟又发生了什么？

希望能对BREW初学者起到一定的帮助，加深对BREW面向

对象接口机制的了解。-Because almost did not elaborate on the mechanism BREW interface documentation, prejudice BREW interface mechanism for learning. So, in conjunction with their feelings and experiences to write the document. This document a complete analysis of the brew in the two kinds of interface methods (Aeeinterface and Qinterface), analysis of the interface What is it? Create interface What happened? The use of the so-called interface function (because in fact the macro) is exactly what happened? The hope is some help to play beginners BREW, BREW deepen their understanding of the mechanisms of object-oriented interface.
