| [Compare] DiffEngine: Modifying when Conflicting EReferences occur [message #118975] |

When running a Diff, I need (non-containment) EReferences to be
evaluated just by the *URIs* they point to. For example, I'd like
references only to appear conflicted if they point to diffent URIs,
irregardless of the content of that Resolved references point to (or
even if the reference is still a Proxy). I believe the current
behavior shows a conflict when the referenced objects aren't "equal".
So, my question would be, what is the best approach to customizing the
DiffEngine behavior in this way? (create a new DiffExtension, extend
GenericDiffEngine, put in a enhancement request for new options passed
to GenericDiffEngine, etc).
Thanks,
Matt

Thanks for the quick reply! I'll reply to this thread if I find issues
extending the GenericDiffEngine.
Thanks again,
Matt

Matt,
I think the best way of defining such a behavior would be to extend
GenericDiffEngine through the extension point
org.eclipse.emf.compare.diff.engine and to override
GenericDiffEngine#checkReferencesUpdates(DiffGroup, Match3Element).
We tried and make the generic diff engine extensible for such needs so
that clients won't need to create a whole new IDiffEngine for trivial
modifications of the generic behavior. Feel free to give us any feedback
you would have about lack of extensibility or functionalities about the
generic engines.
About options that could be passed on to the Differencing engine ...
This could probably be a cool feature but we need to think about how to
implement it if it can be done ;).
Cheers
