# NEDCppGenerator Class Reference
[Generating C++ code]

`#include <cppgenerator.h>`

List of all members.

## Detailed Description

NEDC functionality: generates C++ code from a NED object tree.

Assumes object tree has already passed all validation stages (DTD, basic, semantic).

Uses CppExpressionGenerator.
