Patterns

Capturing a wealth of experience about the of object-oriented software, four top-notch ers present a catalog of simple and succinct solutions to commonly occurring problems. Previously undocumented, these 23 patterns allow ers to create more flexible, elegant, and ultimately reusable s without having to rediscover the solutions themselves. The authors begin by describing what patterns are and how they can help you object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring s in object-oriented systems. With 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 problems most efficiently. Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other constraints, and the consequences and trade-offs of using the pattern within a larger . 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.
