Using policies with the STL
In exploring policy-based design, we’ve established how this design paradigm fosters modularity and flexibility in C++ software components. Now, let’s get into the specifics of how policies can be effectively employed to enhance the functionality and adaptability of STL data types, contributing to more efficient and customized solutions.
Memory allocation policies
One of the most pertinent applications of policies in the context of STL data types is the management of memory allocation. Consider a scenario where you must optimize memory allocation for a specific container, such as a std::vector
instance. By introducing memory allocation policies, you can tailor the container’s memory management strategy to your requirements.
For instance, you may have a specialized memory allocator optimized for your application’s specific use case. Instead of modifying the container’s internal logic, you can seamlessly integrate...
