Hi Beti,
Please take a look at the EMF Compare FAQ
http://wiki.eclipse.org/EMF_Compare_FAQ#Which_files_should_b e_compared_via_EMF_Compare_.3F
and let us know if we need to simplify or elaborate on these explanations.

Hi,
Thanks a lot for your message. But, even after some time spent on the problem, I have still questions about how to use this or that object.
I am working on comparing UML/OCL models. My goal is for example to find the variable definitions or uses that changed into the OCL code. My question is maybe naive, but how can I get my object variable (from my metamodel) which use is changed into the OCL code ( in a operation of my Class Diagram, for instance), once I have called the DiffService.doDiff() operation? Can I just say :
if (diff instance of Variable) {return diff;}
In addition, here is a part of my code :
protected static int getSubchanges(DiffGroup d)
{
int res = 0;
for (DiffElement diff : d.getSubDiffElements()) {
if (diff instanceof DiffGroup) {
System.out.println("diff group : "+((DiffGroup)diff).getRightParent());
res += getSubchanges((DiffGroup)diff);
} else {
System.out.println("nb : "+diff.eClass());
res += 1;
}
}
return res;
}
protected static int getSubchanges(DiffModel self) {
int subChanges = 0;
System.out.println("totot");
for (DiffElement diff : self.getOwnedElements()) {
if (diff instanceof DiffGroup) {
System.out.println("diff group First: "+((DiffGroup)diff));
subChanges += getSubchanges((DiffGroup)diff);
} else {
System.out.println("diff unit sub"+diff.eContents());
subChanges += 1;
}
}
return subChanges;
}
ann in my main :
// Computing differences
DiffModel diff = DiffService.doDiff(match, false);
int nb = getSubchanges(diff);
Sorry, if my question is not very clear.
Thanks in advance!
Best regards,
Beti

Hi Beti
For EMF Compare to give you an intelligent OCL difference you would need
to have your OCL represented by its AST. I suspect that most tools are
currently persisting the OCL as a string.
If you are working within the context of your own Java code, you could
try traversing your model and replacing each String-based expression
with its parsed equivalent.
