Hi,
Maybe it's a simple question..
How observe commit on server side? I find solution only on client side by extension org.eclipse.emf.emfstore.client.commitObserver

Thanks.
Dmitriy.

Hi Dmitriy,

Unfortunately we do not provide a server based callback interface
anymore. We did in the past and you may find these plugins in the
emfstore.other repository (they are called backchannel plugins),
but the API these plugins depend on has been marked as deprecated.

As an alternative solution to your problem you can register adapters on
the EMF server model, e.g. by adding
EAdapters to the ProjectHistory instances. Please find attached some
example code that gets called for all existing projects when a commit
has been registered via the versions property of the ProjectHistory
class (this goes into the EMFStoreController's run(boolean) method)
after initServerSpace() has completed:

for (final ProjectHistory history : serverSpace.getProjects()) {
history.eAdapters().add(new AdapterImpl() {
@Override
public void notifyChanged(Notification msg) {
if
(msg.getFeature().equals(ModelPackage.eINSTANCE.getProjectHistory_Versions()))
{
Version newVersion = (Version) msg.getNewValue();
System.out.println("New version " +
newVersion.getPrimarySpec().getIdentifier()
+ " for project " + history.getProjectName() + " committed.");
}
}
});
}

If the proposed solution above does not fit your needs, we are happy to
provide a dedicated API with one of the next nightly builds. In this
case it would be helpful if you could explain your requirements in more
detail.

Cheers,
Maximilian

Hi Maximilian,
Thanks for detailed answer.

I think it is suitable solution for my task. The point is that we need some codegeneration for our domain model. As model live in EmfStore then codegenration should occur on server side at the same time with commit

Thanks,
Dmitriy
