[EMF Compare]Comparing own model (Dynamic Emf) [message #609705] Thu, 13 September 2007 00:12

Hi,

i want to compare my own datastructure with EMF Compare. Therefore i`ve
written a converter which converts my own datastructure to an EObject. Here
is a snippet:

EPackage pack = EcoreFactory.eINSTANCE.createEPackage();
xdmPackage.setName(model.getRoot().getName());
EPackage firstChild = EcoreFactory.eINSTANCE.createEPackage();
firstChild.setName(model.getRoot().getfirstChild().getName() );
pack.getESubpackages().add(firstChild);

return pack;

Then i call the matching engine.

final MatchModel match = new DifferencesServices().modelMatch(model1,
model2, new NullProgressMonitor());

That will result in an NullpointerException, because their is no resource
binded to the EObject. I didnt find a way to add a resource to an EObject.
How do I do this? And a more important question is, will this work in the
end or do I have an fatal mistake in my logic?

regards,
ChrisW
