Regardless how you create a UML2-based model (using UML2 Tools, Papyrus,
the EMF generated editor), you are going to read it the same way, i.e.
using EMF and UML2 API. So your question is indeed a MDT UML2 question.
The UML2 metamodel implementation works much like any other EMF-based
metamodel implementation. The way you load an EMF-based model into
memory is something like this:
URI modelURI = URI.createURI("uri/to/your/model.uml");
ResourceSet resourceSet = new ResourceSetImpl();
Resource resource = resourceSet.createResource(modelURI);
Once loaded into memory, you can, for instance, traverse through all
named elements in the model using the following code:
for (
TreeIterator<EObject> i = resource.getAllContents();
i .hasNext();
) {
EObject current = i.next();
if (!(current instanceof NamedElement))
i.prune();
NamedElement asNamed = (NamedElement) current;
System.out.println(asNamed.getQualifiedName()
+ " : " + asNamed.eClass().getName());
}
Other than the assumption that model elements are UML NamedElements, the
code above is pretty much based on pure EMF API. Once you get to UML2
specific model elements, then you can extract whatever UML-specific
information you need. See the following Javadoc:
