Extracting the compilation unit info [message #903693]

Hi, all.

I have an XMI java model discovered by MoDisco but I need to extract the info the model is showing on the MoDisco Model Browser, as the image attached.

The code below loads the XMI file and I begin at the root model object: Dc3AdminEJB

Then I iterate over the 43 compilation units trying to know names like the real classes analized by the discoverer like the one in the image attached: BureauCharacteristicBO.java

Resource resource = resourceSet.getResource(uri, true);
		System.out.println("Loaded " + uri + "  " + resource);
		ModelImpl rootModel = null;
		for(EObject n : resource.getContents())
		{
			ModelImpl mo = (ModelImpl) n;
			String rootModelName = mo.getName();
			if(rootModelName.equalsIgnoreCase("Dc3AdminEJB"))
				rootModel = mo;
		}
		if(rootModel != null)
		{
			System.out.println("Model: " + rootModel.getName());
			EList<EObject> an = rootModel.eContents();
			List<EClass> javaClasses = new LinkedList<EClass>();
			for(EObject eo : an)
			{
				EClass eclass = eo.eClass();
				
				String eclassName = eclass.getName();
				//System.out.println("Java class: " + eclassName);
				if(eclassName.equalsIgnoreCase("CompilationUnit"))
				{
					;
					//CompilationUnit a = (CompilationUnit) eclass;
					
					System.out.println("Java class: " + eclass.eResource());
					
					javaClasses.add(eo.eClass());
				}
			}		
			
		}

The problem is that I keep getting the name CompilatioUnit not BureauCharacteristicBO, no matter what method I use.

Tried to cast to CompilationUnit class of the metamodel but it doesn't work:

org.eclipse.emf.ecore.impl.EClassImpl cannot be cast to javamm.CompilationUnit

Any advice on how to extract this info?

Thank you!

Hello Juan,

Have you tried to directly use the references as defined by the Java metamodel to navigate through your Java model?

For instance, from a Model element, there is a reference "compilationUnits" that points to the list of CompilationUnit elements: this could help you to check whether your model has been fully/correctly loaded in memory.

Best regards,

Hugo

Hugo, as always, thank you so much. It worked perfectly navigating through the CompilationUnit list the root model has.

Again, thank you.
