In 1994, Design Patterns changed the landscape of object-oriented development by introducing classic solutions to recurring design problems. In 1999, Refactoring revolutionized design by introducing an effective process for improving code. With the highly anticipated Refactoring to Patterns, Joshua Kerievsky has changed our approach to design by forever uniting patterns with the evolutionary process of refactoring. This book introduces the theory and practice of pattern-directed refactorings: sequences of low-level refactorings that allow designers to safely move designs to, towards, or away from pattern implementations. Using code from real-world projects, Kerievsky documents the thinking and steps underlying over two dozen pattern-based design transformations. Along the way he offers insights into pattern differences and how to implement patterns in the simplest possible ways. Coverage includes: * A catalog of twenty-seven pattern-directed refactorings, featuring real-world code examples * Descriptions of twelve design smells that indicate the need for this book's refactorings * General information and new insights about patterns and refactoring * Detailed implementation mechanics: how low-level refactorings are combined to implement high-level patterns * Multiple ways to implement the same pattern-and when to use each * Practical ways to get started even if you have little experience with patterns or refactoring Refactoring to Patterns reflects three years of refinement and the insights of more than sixty software engineering thought leaders in the global patterns, refactoring, and agile development communities. Whether you're focused on legacy or "greenfield" development, this book will make you a better software designer by helping you learn how to make important design changes safely and effectively.
借鉴《设计模式》与《重构既有代码》,对其中一些见解提出自己的看法,同时对《重构》中的大部分例子进行了详细的说明,是一本通过实际例子提升重构能力的好书 心得:加深了对《设计模式》的理解:一个特定的环境(上下文),一系列类似的问题,还有一个解决办法的结构方式。 重...
評分不要在设计之初就采用复杂的设计模式,这一点我非常认同作者。使用设计模式是为了应对变化。在设计阶段难以预见系统变化。推荐采用简单的设计模式,例如工厂方法和组合方法。 这本书告知读者,复杂的设计模式(例如访问者)产生于不断重构。在重构过程中完善系统设计,应对未来...
評分重构与模式还有极限编程,我根本不会指望从书本中入门。 一个项目,几个项目之间总结出的经验,然后回过头来看看这些书,也许会有些共鸣,或者修补一些经验的遗漏,至于入门,领会了皮毛只会造成滥用,最近在看ajax设计模式,尤其有这种感觉,一种理论,从形成到滥用的...
評分之前看过不少有关设计模式的书,《java与模式》,《Head First Design Patterns》,《重构:改善既有代码的设计》。 但是这本《重构与模式》,确实最实在的一本。《重构》从最基本的最常用最简单的重构方法开始介绍,实在是受益良多,对以前对设计模式的理解加深了很多,终于...
評分之前还没看过模式那本书,所以不知道那些模式。 现在看完只是对重构有一部分的了解,因为里面的代码为Java,而我是用objective-c的,但代码都是通用的。只能在之后看完了重构和模式两本书以后再回头看,应该会有更深刻的了解。 现在对项目的重构有了一点的帮助,很好。
在《重構》的基礎上進一步闡述瞭重構和模式之間的關係,並提供瞭嚮模式重構的思路和步驟,非常贊的一本書!

评分連接起Martin Fowler之Refactoring與GoF之Design Patterns的橋梁。展現瞭如何在重構過程中運用模式的經驗,不過模式類的書始終需要實踐纔能學得通。
评分立意很好,可總覺得這書寫得太晦澀瞭,另外書中本就殘缺的源碼竟然網上沒有完整的免費下載!
