内容概要

利用经验累积而得的洞察力开发新的解决方案被称为预构。透过重构而获得的专业知识也属于这类经验，而预构的词源即重构。重构是修改程序或软件系统内部结构的实践，以此在保留其现有行为的基础上改良设计。重构的原因有多种：方便后期增加功能、提高可维护性、提升性能。     本书作者是经验老道的软件开发人员。书中，作者运用他个人和其他众多开发人员的丰富经验，展示由其推衍而得的各项实践方针。这些方针把优秀的开发人员在设计时隐而未显的考虑细节如实地呈现出来。许多方针都围绕着极致抽象化、极致隔离以及极致可读性这几个概念。在假想的软件项目和实际项目的介绍中，作者把实践方针呈现在读者面前。其中几条于稍后列出。     把作者的方针应用到你的软件项目，有助于写出可读性、可维护性更棒的程序。这些方针可以协助你前期决策，以减少后期重构的工作量。在这样的前提下，你可以预测未来，减少修改。简言之，就是程序预构会使你更有效率。

•   我们都在coding,我们都在re-factoring,,那么在coding和re-factoring之间我们应该干什么?这本书的视角独特,可细看进去,我们要做要注意的其实还是那些事情.
•   视角不错！不愧获得06Jolt震撼大奖！把研发项目中客户的参与很形象地表达出来，英语表达清楚简练，案例规模适中，很多经验总结得简要、清楚！在自然而然中，道出了软件设计研发的要义。
•   pre-factoring理解为重构的反义词就可以了。老美就是喜欢造新词
