Metafunctions

| Metafunctions Metafunctions - also known as "traits" or "trait classes" - return types, constants or functions for a set of given types or constants. They can be seen as part of a (meta-)program that is evaluated at compile time to produce a C++ program. Read here an introduction to metafunctions and how to use them. Metafunctions
