Comparing Objects with EMFCompare [message #1137621]

Hi there

This is my question, I am comparing two different projects V1 V2
A possible representation of V1 and V2 could be something like this:

A->B->C
'-> D

A->F->B->C
'-> D

Because of the particularities of my models B can be moved into another object in this case F. At this point EMF compare wil tell me somthing like this:

"The object B has been removed"
"The object F has been added"

This is true but only from the point of view of the location of the objects inside the two models, but from the point of view of the logic B has been just moved into another position. Now it is my task confirm that this is like this. This is where I wonder if I can use EMFCompare to compare two OBJECT rather than two models, because it is possible than the B Object has been relocated but it is also possible that this object has been modified or really cancelled.

Can I use the framework to do something like this?

Regards

Hi,

This is not possible with EMF Compare 1.3 since that was one of the key limitations of that version. EMF Compare 1 cannot detect changes "under" an added or deleted element, in your case, F.

Please use EMF Compare 2.1 for needs such as this one.
