#  | The Token Identifiers |

> Table of literal token identifiers
> Table of white token identifiers
> Table of keyword token identifiers
> Table of operator token identifiers
> Table of preprocessor token identifiers

The following tables contain all those tokens, which should be recognized by a C++ lexer, which is to be used in conjunction with the `Wave` preprocessing engine. The tokens are grouped into categories to simplify some internal logic and eventually the driver programs. The token identifiers are defined as an `enum`, and it is recommended to reuse this definition for your own lexer implementations.

Note though, that the preprocessor engine does some token transformation, so that not all of the listet here token identifiers may occur inside tokens, returned from the preprocessing iterator.

The preprocessor tokens listet in the following table are returned by the C++ lexer only. The preprocessor naturally acts on these tokens and they are not returned by dereferencing the preprocessing iterators.
