Capturing a wealth of experience about the design of object-oriented software, four top-notch designers present a catalog of simple and succinct solutions to commonly occurring design problems. 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 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. All 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.
Design Patterns is an exhaustive guide on designing reusable object-oriented software.
Summary of the Book
Design Patterns: Elements of Reusable Object-Oriented Software is a comprehensive book which will help the readers design object-oriented software. The book comprises of chapters on designing a document editor, designing creational patterns, structural patterns and behavioral patterns. This book presents a catalog of simple solutions to the commonly occurring problems associated with designing. These patterns will allow designers to create flexible and reusable designs. Design Patterns provides valuable information on how these patterns fit into the software development process and how they can be used to solve design-oriented problems more efficiently.
