Design Patterns: Elements of Reusable Object-Oriented Software
ამ ელწიგნის შესახებ
Patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves. Highly influential, Design Patterns is a modern classic that introduces what patterns are and how they can help you design 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 design constraints, and the consequences and trade-offs of using the pattern within a larger design
- 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 design patterns and have had an ‘Aha!’ (and not just a ‘Huh?’) experience with them, you won't ever think about object-oriented design in the same way. You'll have insights that can make your own designs more flexible, modular, reusable, and understandable - which is why you're interested in object-oriented technology in the first place, right?”
