- What is the Strategy pattern?
The Strategy pattern is a behavioral pattern that allows the user to customize a certain aspect of the behavior of the class by selecting an algorithm that implements this behavior from a set of provided alternatives, or by providing a new implementation.
- How is the Strategy pattern implemented at compile time using C++ generic programming?
While the traditional OOP Strategy applies at runtime, C++ combines generic programming with the Strategy pattern in a technique known as policy-based design. In this approach, the primary class template delegates certain aspects of its behavior to the user-specified policy types.
- What types can be used as policies?
In general, there are almost no restrictions on the policy type, although the particular way in which the type is declared and used imposes certain restrictions by convention. For...
