In aggregation (City, Tree, Car) “sub objects” (Tree, Car) will NOT be … Read more

You can use them to ensure your use cases are sufficiently robust to represent usage requirements for the system you’re building. They involve: Actors Use Cases Entities Boundaries Controls Whereas the Model-View-Controller pattern is … Read more

My current preference. EclipseUML from Omondo. Only commercial versions appear to be available right now. The class diagram in your question, is most likely generated … Read more

Hmm, this seems to be a bit of an old question, but since I’ve been messing about with Doxygen configuration last few days, while my head’s still full of current info let’s have a stab at it – I think the previous answers almost have it: The missing option is to add COLLABORATION_GRAPH = YES … Read more
