Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves. 　　 The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns: Elements of Reusable Object-Oriented Software as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently. 　　 Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. AII patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk. 英文版《Design Patterns:Elements of Reusable Object-Oriented software》目录： preface foreword guide to readers 1 introduction 1.1 what is a design pattern? 1.2 design patterns in smalltalk mvc 1.3 describing design patterns l.4 the catalog of design patterns 1.5 organizing the catalog 1.6 how design patterns
