Here’s a small snippet of code to load an Ecore resource without having to initialize all the necessary packages needed to read all elements. This is useful if we’re interested in only a subset of the schema elements that are present in the Ecore model.
public static EList open(File file) throws IOException { ResourceSet resourceSet = new ResourceSetImpl(); //Initialize the FSML Package information (ie. URI) MyPackageImpl.init(); //Set OPTION_RECORD_UNKNOWN_FEATURE prior to calling getResource Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put( "*", new EcoreResourceFactoryImpl() { @Override public Resource createResource(URI uri) { XMIResourceImpl resource = (XMIResourceImpl) super.createResource(uri); resource.getDefaultLoadOptions().put(XMLResource.OPTION_RECORD_UNKNOWN_FEATURE, Boolean.TRUE); return resource; } }); XMIResource resource = (XMIResource) resourceSet.getResource( URI.createFileURI(file.toString()), true); //Unknown elements will appear in this map System.out.println(resource.getEObjectToExtensionMap()); resource.load(Collections.EMPTY_MAP); return resource.getContents(); }
Be aware that any unrecognized elements will be null in the retrieved Ecore model.
