GoF (Gang of Four) Design Patterns is one of the most popular subjects for programming classes out there. Even though the original book provided coding examples written in C++ and Smalltalk, those patterns are most useful in pure OO programming languages (like Java or C#).
This training provides an alternative approach to this subject. First, it discusses the art of a good overload set and class design in detail. In this part of the training, we learn that less is better, how non-member functions influence class encapsulation, what const keyword have in common with multithreading, and many other essential design principles. When we know how to form a well-behaved class properly, we learn a long list of C++-specific idioms that are useful in everyday jobs and are not included in the GoF book. After that, the training thoroughly covers the subjects of inheritance, polymorphism, and value semantics. Ultimately, it describes all of the GoF design patterns, presents their intended use cases and implementation, and confronts that with Modern C++ criticism and possible alternatives. Training includes examples of correct and incorrect implementation of the most popular patterns. As part of the practical exercises, participants have the opportunity to learn about the benefits and the consequences of using each of the approaches.
The training targets C++ developers and code architects who want to improve their skills in designing interfaces and proper class interaction.
This course builds on top of the knowledge delivered in Modern C++ Design: Part I - Stable and Secure Code training, so please consider requesting them in this order.
TRAINING HIGHLIGHTS
- Emphasis on understanding different use cases of inheritance in C++ language and learning how to reuse this knowledge in own code
- Understanding the differences between inheritance and polymorphism
- Learning of different C++ idioms and patterns and their use cases
- Particular focus on the usage of "C++ templates" in practical tasks
- Development of error-unfriendly code
