Distinguishing various references inside Diff with same name [message #1827411]

Hi,
I'm quite new to EMF and have recently started using EMFCompare programatically to compare models in a 2-way comparison. So far, I'm beginning to have a global understanding of the way EMFCompare works and how the Diffs represent the differences between the models.
However, I have a problem. Suppose I have a model with three classes A,B and C. Both class A and B have a reference named c going to C, those references being indentical to the exception one is in A and the other in B. If I operate a modification on one of the references c, let's say I change the name of the one in A, EMFCompare is going to inform me of this with a CHANGE Diff. My problem is I don't know how to know (from this Diff) which reference was changed. Is there a way to get this information programatically from the various informations EMFCompare can give us ?
Thanks for your help.

Hello,
On the Diff you can retrieve the Match, from which you can navigate to the object that has been changed, in your case this object should be the reference that has been renamed.
