The Observer Design Pattern in C++

Explore the Observer Design Pattern in C++ through this comprehensive conference talk from CppCon 2022. Delve into the behavioral design pattern that allows objects to monitor state changes in other objects, commonly used in event handling systems for games, desktop software, and mobile apps. Learn how to implement the Subject and Observer (publisher and subscriber) model to create more maintainable, extensible, and flexible software. Examine real-world use cases, modern C++ examples, and discuss the pattern's tradeoffs. Gain the knowledge to implement the Observer pattern and identify it in existing projects. Presented by Mike Shah, an Associate Teaching Professor at Northeastern University with extensive experience in computer systems, graphics, and software engineering.
