E.3. Generator Application Source Reference
The source code reference documentation is also part of the openETCS domain framework
reference documentation in Section D.1.
E.4. Generator Model
The UML model is also part of the openETCS domain framework model in Section D.3.
E.5. Generator Source Code
The source code is also part of the openETCS domain framework source code in Section D.2.
The following C++ source code listings are used as examples for the main part of this document.
