WebAug 31, 2013 · One (and most used) technique in C++ is Pimpl idiom (“pointer to the implementation”). It is simple but extrem effective. It is based on two facts: a pointer to an object has always the same size (on the same compiler-version and platform) class-forwarding make it possible that you don’t have to include the header-file for the … WebDec 27, 2024 · The PImpl Idiom (Pointer to IMPLementation) is a technique used for separating implementation from the interface. It minimizes header exposure and helps programmers to reduce build dependencies by moving the private data members in a separate class and accessing them through an opaque pointer.

Pimpl For Compile-Time Encapsulation (Modern C++)
WebPIMPL may have had a side-effect of reducing compile times and people may have used it for that purpose, which modules kind-of solve. I say kind-of, because the moment you want to support people using your library with pre-C++20 code, a lot of what you can do with modules disappears. But that's a tangent not worth getting into. WebMar 16, 2024 · The Pimpl pattern is normally used to hide implementation details of a class, so that only the public interface and a single pointer to the implementation is left.
