C++ Glossary

There are a number of C++ acronyms that I seem to forget over and over, so i decided to start maintaining a glossary here. I hope others find this useful, as well.

pImplPointer to Implementation“Pointer to implementation” or “pImpl” is a C++ programming technique[1]┬áthat removes implementation details of a class from its object representation by placing them in a separate class, accessed through an opaque pointer.

This technique is used to construct C++ library interfaces with stable ABI and to reduce compile-time dependencies.
