Hi Noureddine,
Here are my two cents:
- Regarding the Java IDE (v3.0), you could check an overview
here. If you are looking to automatically generate UML diagrams from the sources,
here and
here are listed some tools to reverse engineer existing Java code. See as an example the package diagram here attached.
- Concerning the C++ Core code (v3.0), an overview is
accessible here.
if you make any progress in creating a conceptual diagram, please feel free to share it with us here!
Regards,
