Hi,

I am switching from CDO to EMFStore and the tutorials do not provide much in the way of instruction for how to version a model programatically. Is there an example somewhere? "EMFStore Code Examples" are rather simplistic.

I assume it is based around VersionSpecImpl?

Hi David,

we will get back to you about this question, but due to holiday season,
it might take until next week.

Best regards

Jonas

Hi David,

sorry for the delayed reply, we have all been on vacation.
I agree the examples are rather simplistic but that is unfortunately the best documentation
available other than the JavaDoc. The API tutorial shows how to share, commit and update on a project.
I am not sure what you refer to by versioning a model but IMHO ESLocalProject has most of the
relevant methods. You can commit a changed model and update the model with changes from the server
including merging in the face of a conflict. It also tells you the current version of the local
project with getBaseVersion(). To query the history (including all previous versions) and branches
of a project in the server you can get the ESRemoteProject from a ESLocalProject with
getRemoteProject and make calls on it:
http://download.eclipse.org/emfstore/releases_16/javadoc/org/eclipse/emf/emfstore/client/ESLocalProject.html

BTW: May I ask why you switch from CDO to EMFStore?

Hope this helps!

Cheers,
Maximilian
