Using Eclipse UML2 to parse a Visual Paradigm generated XMI file

I have drawn a class diagram by Visual Paradigm 8 and exported the project as XMI 2.1 file (Export for UML2). so there are two files (test.xmi.uml and test.xmi.profile.uml). To parse test.xmi.uml I wrote this java code using eclipse uml2 and emf:

ResourceSet set = new ResourceSetImpl();
set.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
set.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
Resource res =  set.getResource(URI.createFileURI("C:\\test.xmi.uml"), true);
EObject eobj = res.getContents().get(0);

but the output object (eobj) is an AnyTypeImpl which can't be read very well. what should I do to get well formatted objects like org.eclipse.uml2.uml.Model objects by parsing this file?

Solution

  • I have finally found my answer: Using org.eclipse.uml2.uml.resources.util.UMLResourcesUtil.init() to initialize the parameters needed to parse the .uml file. So the code must be like this:

    ResourceSet set = new ResourceSetImpl();
UMLResourcesUtil.init(set);
Resource res = set.getResource(typesUri, true);
EObject eobj = res.getContents().get(0);

    the eobj is an instance of org.eclipse.uml2.uml.Model which is a well-formed object.
