Compare 2 EObjects with that same model [message #1053777]

Hello,

I am looking to compare 2 EObjects. These 2 EObjects are from the same data model. All I am looking for is something (relatively simple) that will return some kind of structure, like the following.

DiffStructure diffObject = EMFDiff.(eObject1, eObject2);

I would then be able to recurse the diffObject to find what has changed from the 1st object (object1) to the second (object2).

Does something close to this exist? EMFCompare seems to compare differences in models? I am looking to compare two EObjects from the same model.

Any information on this will be appreciated.

Thanks
-Andy

Andrew,

See the FAQ. Though the code sample uses URIs and Resources to create the comparison scope, you can use plain EObjects instead. All you need is to replace the line

IComparisonScope scope = EMFCompare.createDefaultScope(resourceSet1, resourceSet2);

with

IComparisonScope scope = EMFCompare.createDefaultScope(leftEObject, rightEObject);
