The Strategy Design Pattern in Cpp - Mike Shah - C++Online 2024
The strategy design pattern is a fundamental behavioral design pattern allowing clients to control the behavior of an object at run-time. The strategy pattern can be seen in action in the C++ STL for example applying 'policies' to how to execute operations (e.g. std::par or std::seq as one example) -- thus strategy is often known as the 'policy pattern' as well. The strategy design pattern is commonly used to choose the algorithm at run-time to best solve a problem -- separating the algorithmic behavior from the object itself to help make our software more maintainable, extensible, and flexible. In this talk, we will look at a series of C++ examples (starting from scratch) of using the strategy pattern to deploy different algorithms at run-time. We will also look at examples of code in libraries deploying the strategy pattern, and talk about best practices for using the strategy pattern in Modern C++. The strategy pattern will also be compared to the Template Method Pattern, which may be an alternative choice. Attendees will leave this talk with the knowledge to go forward and implement the strategy pattern, as well as how to spot the strategy design pattern in projects they may already be working on!
