Why are .ecore models loaded into each session resource set? [message #1480539] Thu, 20 November 2014 09:07 Go to next message

Hi,

When I look at a session ResourceSet at runtime, I note that its
resources include all our semantic models. Do I understand correctly
that each session resource set loads in a copy of the semantic ecore
models? Why is that needed? Wouldn't it be sufficient to just rely on
the global package registry which already provides access to the
required semantic EPackages?

I think that you reference your meta-model in your VSM (.odesign file).
So when EMF loads your VSM, it also loads your meta-model.

The problem is that the metamodel "references" are stored with a href (a
link to the root of the MM). A better solution would be to only store a
String attribute that Sirius interprets when needed.

Regards,

Laurent

Follow up Question:
My resource set have nothing in there. I am using the following code:
siriusSession= SessionManager.INSTANCE.getSession(URI.createURI(projectName+"/"+airdFile), new NullProgressMonitor());

The above code returns a session object with no semantic resources and with nothing inside DAnalysis.
Can some one please tell me what's wrong?
Bellow is some part of the .aird file

Hi,

You called SessionManager.INSTANCE.getSession() which created the session but did not open it.
You now need to open the session, for example: session.open(new NullProgressMonitor();

Note that you might also directly ask the SessionManager to create and open the session: session = SessionManager.INSTANCE.openSession(representationsFileURI, new NullProgressMonitor(), SiriusEditPlugin.getPlugin().getUiCallback());

Regards,


or after
