【Agile Pair Coding】Data Type Mapping
介紹
今天下午用了1個小時左右，和同事Agile Pair Coding敏捷開發了一把，感覺挺爽的。
Agile Pair Coding給我們帶來的直接好處是：相互不浪費時間(就兩個人)，高效；idea很快達成共識(就兩個人)，不糾結於無謂的討論；idea立馬coding，不沉迷於頭腦風暴；代碼更嚴謹；重構概率大；加深基情；相互學習，相互欣賞，相互指正；避免無知，避免自我感覺良好......
代碼主要實現：從所有類型文件中，得到所有NE類型下的所有Object類型下的所有屬性的數據類型。
當然，本文隻是一個短時間內的Draft版本，可能會有一些問題，敬請指正。
