Hi,
This is my first time using EMFCompare so i need help to understand it.
I used compare with to compare two UML models(deployment diagrams) and when i saved the output of the comparison i got text file .
I have two questions first what is the default editor for that file in order to view the file in a correct way is it text editor or Trace file viewer?

Second is there a metamodel for that comparison output so i can follow it to understand the resulted file .I need to understand the output of the comparison(text file) to be able to query the output of the comparison which i saved as text file .

Thanks,
Taghreed.

Hi,

to my knowledge, there is no dedicated editor for exported comparison models. You could just open it with Sample Reflective Ecore Editor though, because the comparison model is an EMF-based model.

The metamodel of the comparison is in org.eclipse.emf.compare/model/compare.ecore. In the developer guide, there is an overview of the comparison model.

Best wishes,

Philip

Thanks i got the metamodel.
How can i save the output of comparison in a format that i can query I need to query the result of comparison.For example how can i query Diff class to get its properties such as kind .In text file some properties are missing and i need to retrieve its values.
Can you please help me.

Thanks,
Taghreed

Hi,

I don't think that there is a way of storing the comparison model from the IDE UI (probably because the comparison model is not self-contained but needs the compared model versions to make sense). You could store the comparison model just like any other EMF resource, after you started the comparison using the EMF Compare API. However, in the EMF Compare developer guide there is no section, which explicitly shows how to start a comparison from a Git repository using the EMF Compare API.

Depending on what you want to do, it could be easier to write a plug-in that obtains the comparison model from an opened comparison editor. So you would start the comparison as usual and then start your plug-in, which obtains the editing domain of the comparison editor, which contains the comparison model, and do whatever you wanted to do.

Once, you have your comparison model in memory, you can query it, just like any other EMF model and obtain all the information about the differences, as given in EMF Compare's comparison model.

Best wishes,

Philip

Hi Philip,
My goal is to record all changes i have made on my source model i mean UML model because my long term goal is to propagate that changes to other model .
That's why i need to be able to query the comparison model .
Can you please provide me with any any tutorials that can help me.For example how to write plugs-in.

Thanks,
Taghreed
