Source code header file written in the C++ programming language; may include data types, constants, variables, and other definitions; used for declaring and storing reusable components of code.

More Information

HXX files can be inserted into a C++ program using the #include directive. For example, #include myHeader.hxx instructs the C++ compiler to include "myHeader.hxx" into the current program file.

NOTE: C++ header files are more commonly seen with the .HPP extension.
