[news.eclipse.technology.emft] [EMF compare] merging explanation

[philipp kalb <mugbi83@xxxxxxxxxxxxxx>]

Hi

After some time searching for good model comparison software I came 
across EMF compare. From what I have seen so far it is really a great 
piece of work but sadly the documentation could not answer all of my 
questions. I hope that you can fill these gaps.

I had no problems with matching elements and using the difference engine 
to get a match- and diffmodel (I used the standalone example and EMF 
models). I understand how this works but after these steps I want to 
merge both models. This seems to be a very tricky part.

So my actual question is: what happens when calling 
MergeService.merge(....) ? Does this really merge the left and the right 
model (according to the Boolean parameter and the diffs), are these 
changes also stored in the ResourceSet? Does merge use the diffs and the 
two models in the resource set?

Is it possible to store the diff-/matchmodels and apply the changes 
later,  without loading both models but only one of them? Like: Store 
the snapshot, store the left model; two days later apply the merging on 
he left model (the right model was deleted). Is this possible?

I hope my questions are not too confusing
Thanks for your attention,
Best regards
 Philipp
