refactoring笔记——代码重构的方法目录

Refactorings in Alphabetical Order

This is a simple list of refactorings both from the original book and some later sources. Sadly I haven't had enough time and energy to keep this material up to date. Refactorings marked with  with have some extra material to what's in the Refactoring book. Refactorings marked with  are in addition to those in the refactoring book. Refactorings with Link Only are references to refactorings described elsewhere.

Unless otherwise indicated refactorings in this section are described by me (Martin Fowler). Other refactorings are marked with their authors. I have not given these refactorings any detailed review, if you find issues with the refactorings, please get in touch with the author and cc me. Neither Martin Fowler, Addison-Wesley, nor any of the authors imply any warranty with these refactorings.
