本书以作者自身学习、使用模式和多年来为软件开发人员(包括面向对象技术老兵和新手)讲授模式的经验为基础撰写而成。首先概述了模式的基础知识,以及面向对象分析和设计在当代软件开发中的重要性,随后使用易懂的示例代码阐明了12个最常用的模式,包括它们的基础概念、优点、权衡取舍、实现技术以及需要避免的缺陷,使读者能够理解模式背后的基本原则和动机,理解为什么它们会这样运作。
本书适合软件开发专业人士,以及计算机专业、软件工程专业的高校师生阅读,也可作为面向对象分析与设计课程的参考教材。
"One of the great things about the book is the way the authors explain concepts very simply using analogies rather than programming examples--this has been very inspiring for a product I'm working on: an audio-only introduction to OOP and software development." --Bruce Eckel "...I would expect that readers with a basic understanding of object-oriented programming and design would find this book useful, before approaching design patterns completely. Design Patterns Explained complements the existing design patterns texts and may perform a very useful role, fitting between introductory texts such as UML Distilled and the more advanced patterns books." --James Noble Leverage the quality and productivity benefits of patterns--without the complexity! Design Patterns Explained, Second Edition is the field's simplest, clearest, most practical introduction to patterns. Using dozens of updated Java examples, it shows programmers and architects exactly how to use patterns to design, develop, and deliver software far more effectively. You'll start with a complete overview of the fundamental principles of patterns, and the role of object-oriented analysis and design in contemporary software development. Then, using easy-to-understand sample code, Alan Shalloway and James Trott illuminate dozens of today's most useful patterns: their underlying concepts, advantages, tradeoffs, implementation techniques, and pitfalls to avoid. Many patterns are accompanied by UML diagrams. Building on their best-selling First Edition, Shalloway and Trott have thoroughly updated this book to reflect new software design trends, patterns, and implementation techniques. Reflecting extensive reader feedback, they have deepened and clarified coverage throughout, and reorganized content for even greater ease of understanding. New and revamped coverage in this edition includes * Better ways to start "thinking in patterns" * How design patterns can facilitate agile development using eXtreme Programming and other methods * How to use commonality and variability analysis to design application architectures * The key role of testing into a patterns-driven development process * How to use factories to instantiate and manage objects more effectively * The Object-Pool Pattern--a new pattern not identified by the "Gang of Four" * New study/practice questions at the end of every chapter Gentle yet thorough, this book assumes no patterns experience whatsoever. It's the ideal "first book" on patterns, and a perfect complement to Gamma's classic Design Patterns. If you're a programmer or architect who wants the clearest possible understanding of design patterns--or if you've struggled to make them work for you--read this book.
优秀代码的目标: * 高效 * 健壮 * 灵活 * 无冗余 * 可读 * 可测试 面向对象的一些原则和方法 * 内聚性(cohesion):例程中操作之间联系的紧密程度 * 耦合性(coupling):两个例程之间联系的紧密程度 * 软件开发的目标:高内聚、松耦合 * 发现变化并将其封装 ...
评分作者从面向对象到设计模式进行了关联解析。重点着笔两处: 1.模式可以解决一些传统oop不能很好处理的问题 2.模式如何连用,即模式的多组合使用 通过几个案例,从无模式的设计方案到有模式后的方案对比讲解了第一点。 同时过程中就介个常用的模式的串用进行了讲解,还给出了作者...
评分您好,我是王同学(北京)13581670712,想问您一下这本书是否还有?我想购买这本书,十分感谢!
评分如果你认为GOF的经典名著《设计模式》太晦涩难懂,《Head First Design Pattern》又太不技术书籍了,那么这本《设计模式解析》非常适合你!这本书每章结束时都有小结和启发性复习题,可以帮助你更好地了解自学得如何了。本书只介绍了几种比较常用简单的设计模式,因而在学习过...
