Patterns

The Gang of Four‘s seminal catalog of 23 patterns to solve commonly occurring problems Patterns allow ers to create more flexible, elegant, and ultimately reusable s without having to rediscover the solutions themselves. Highly influential, Patterns is a modern classic that introduces what patterns are and how they can help you object-oriented software and provides a catalog of simple solutions for those already programming in at last one object-oriented programming language. 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 Is compiled from real systems and based on real-world examples Includes downloadable C++ source code that demonstrates how patterns can be implemented and Python From the preface: "Once you the patterns and have had an ‘Aha!‘ (and not just a ‘Huh?‘) experience with them, you won‘t ever think about object-oriented in the same way. You‘ll have insights that can make your own s more flexible, modular, reusable, and understandable - which is why you‘re interested in object-oriented technology in the first place, right?"
