【Agile Pair Coding】Data Type Mapping

标签：des   style   blog   http   color   java   os   io   

介绍

    今天下午用了1个小时左右，和同事Agile Pair Coding敏捷开发了一把，感觉挺爽的。

    Agile Pair Coding给我们带来的直接好处是：相互不浪费时间，高效；idea很快达成共识，不纠结于无谓的讨论；idea立马coding，不沉迷于头脑风暴；代码更严谨；重构概率大；加深基情；相互学习，相互欣赏，相互指正；避免无知，避免自我感觉良好......

    代码主要实现：从所有类型文件中，得到所有NE类型下的所有Object类型下的所有属性的数据类型。

    当然，本文只是一个短时间内的Draft版本，可能会有一些问题，敬请指正。
