Hi guys,

I done comparison of two models Ecore (m1.ecore and m2.ecore) successfully with EMF Compare 3.0. But, now I need compare two "feature model" (model.yafm - is generated with plugin from eclipse https://bitbucket.org/jpikl/yafmt/overview) with EMF Compare. I have this code:

ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("yafm", new GenericXMLResourceFactoryImpl());
String string1 = "/path1/daigram.yafm";
String string2 = "/path2/daigram.yafm";
URI uri1 = URI.createFileURI(string1);
URI uri2 = URI.createFileURI(string2);
Resource resource1 = resourceSet.getResource(uri1, true);
Resource resource2 = resourceSet.getResource(uri2, true);
IComparisonScope scope = new DefaultComparisonScope(resource1, resource2, resource1);
Comparison comparison = EMFCompare.builder().build().compare(scope);
EMFComparePrettyPrinter.printComparison(comparison, System.out);


and I have this response:

Matched resources :
Left = file: /path1/daigram.yafm
Right = file:/path2/daigram.yafm

+----------------------------------------+----------------------------------------+----------------------------------------+
| Left | Right | Origin |

CONFLICTS


I need to obtain the detail of the information with EMFComparePrettyPrinter.printMatch(comparison, stream). Is this possible? How I can do?
I donĀ“t have any problem with ecore diagrams, but with other diagrams I can't obtain the correct answer.


Thanks in advance for your help.

Regards.

Hi Julio,

I'm not sure I understand your question. I assume that the output of printMatch you got from the pretty printer does not satisfy you. Here is the explanation.

EMF Compare does not handle org.eclipse.emf.ecore.xml.type.AnyType very well. Also, I think that the GenericXMLResourceFactoryImpl creates models with Feature Maps which are not handled by EMF Compare.

To handle AnyType, you may have to create a custom equality helper as stated in the FAQ http://www.eclipse.org/emf/compare/doc/21/FAQ.html#Custom_data_types_are_always_marked_as_modified_by_EMF_Compare

For FeaturesMaps, it has to be implemented in the core engines. This is planned to be done after Luna.

Best.
Mikael
