[Compare] Comparing methods [message #102187]

Hello!

I'd like to ask if is (or will be) some possibility to influence comparing
emf objects. For example lets have two objects : A{property p1 = 1,p2 =1;}
B{property p1 = 1,p2 =2;}
In first case I want to compare all properties , so result will be : object
are not similar.
In second case I want to compare only against first property , so result
will be : object are similar.

I've looked in org.eclipse.emf.compare.match.statistic.DifferencesServices.
Also, I tried to extend class to override some methods like isSimilar, but
it seems to be not optimal way.

Thank you in advance!

Ivo,

Well in fact, method "DifferencesServices#isSimilar" is accessible for
this kind of needs, just call super.isSimilar() for the objects you
don't want to be compared by their first property ;).

You will then have to extend the extension point
"org.eclipse.emf.compare.match.engine" to have your match engine used.

I you can think of a better way to alter the way objects are detected as
similar, do not hesitate to give us your thoughts :).
