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. 0201633612B07092001

A catalog of solutions to commonly occurring design problems, presenting 23 patterns that allow designers to create flexible and reusable designs for object-oriented software. Describes the circumstances in which each pattern is applicable, and discusses the consequences and trade-offs of using the pattern within a larger design. Patterns are compiled from real systems, and include code for implementation in object-oriented programming languages like C++ and Smalltalk. Includes a bibliography.

Der Bestseller von Gamma und Co. in komplett neuer ÜbersetzungDer Klassiker für alle ProgrammiererDas Standardwerk für die objektorientierte Softwareentwicklung Mit Design Patterns lassen sich wiederkehrende Aufgaben in der objektorientierten Softwareentwicklung effektiv lösen. In diesem Buch stellen die Autoren einen Katalog einfacher und prägnanter Lösungen für häufig auftretende Problemstellungen vor. Diese 23 Patterns ermöglichen flexiblere, elegantere und wiederverwendbare Designs, so dass Problemlösungen nicht jedes Mal aufs Neue entwickelt werden müssen. Bei jedem Pattern ist angegeben, in welchem Kontext es besonders geeignet ist und sinnvoll eingesetzt werden kann.
