Synopsis

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 refactoringDetailed 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.

From the Back Cover

Advance Praise for Refactoring to Patterns

"For refactoring to be valuable it must be going somewhere, not just an abstract intellectual exercise. Patterns document program structures with known good properties. Put the two together and you have Refactoring to Patterns." Kent Beck, Director, Three Rivers Institute

"In the GoF book we claimed that design patterns are targets for refactorings. This book finally shows that we didn't lie. By doing so, Joshua's book will deepen your understanding of both refactoring and design patterns." Erich Gamma, Eclipse Java Development Tools lead, IBM

"Refactoring to patterns is a revolutionary approach to applying patterns that combines the top-down utility of design patterns with the bottom-up discovery of iterative development and continuous refactoring. Any serious software developer should be using this approach to discover new opportunities to use patterns to improve their code." Bobby Woolf, Consulting I/T Specialist, IBM Software Services for Web- Sphere, and coauthor of Enterprise Integration Patterns (Addison-Wesley) and The Design Patterns Smalltalk Companion (Addison-Wesley).

"With this unique catalog of design-level refactorings Joshua Kerievsky has given refactoring an entirely new dimension. Refactoring to Patterns shows developers how to make design-level improvements that simplify everyday work. This book is an invaluable reference for the refactoring practitioner." Sven Gorts

"This book refactors and restructures GoF, and much more. Refactoring to Patterns takes a subject that has been presented as static and rigid and makes it dynamic and flexible, converting it into a human process with experiments, mistakes, and corrections so you understand that good designs do not occur by turning some series of cranks--they evolve through struggle and reflection. Kerievsky has also restructured the presentation to make it far clearer and easier to assimilate. Indeed, he has solved a number of the organization problems that I have struggled with in Thinking in Patterns. This book is a clear introduction and combination of the disciplines of testing, refactoring, and patterns, and it is filled with easy reading, good sense, and great insights." Bruce Eckel, President of Mindview, Inc., and author of Thinking in Java/Thinking in C++ (Prentice Hall)

"The first time I met Joshua, I was struck by the depth of his passion for understanding, applying, and teaching design patterns. Great teachers care deeply about their subject and how to share it. I think Joshua is a great teacher--and developer--and that we can all benefit from his insight." Craig Larman, Chief Scientist, Valtech, and author of Applying UML and Patterns, Second Edition (Prentice Hall) and Agile and Iterative Development (Addison-Wesley)

"Refactoring to Patterns is important not only because it provides step-by-step instructions on how to improve your code through the methodical introduction of appropriate patterns, but more so because it teaches the principles that underlie the design patterns implemented. This book should be useful for novice and expert designers alike. This is a great book." Kyle Brown, IBM Software Services for WebSphere, and author of Enterprise Java™ Programming with IBM® WebSphere®, Second Edition (Addison-Wesley)

"Mastering a trade means more than just having the right tools--you also need to use them effectively. Refactoring to Patterns explains how to wield industrial-strength design tools with the skills of an artist." Russ Rufer, Silicon Valley Patterns Group

"Josh uses patterns to guide the small steps of refactoring toward larger goals and uses refactoring to introduce patterns into your code as it evolves. You'll learn how to make large improvements to existing code incrementally, rather than trying to force-fit a prefabricated solution. As the code changes you'll go beyond seeing better designs--you'll experience them." Phil Goodwin, Silicon Valley Patterns Group

"Now the connection between software patterns and agile development is finally told." Ward Cunningham
