Control Referenced Resource Loading [message #226969]

Hello,

I have a set of models which reference between them.

Model A
ref Model B1
ref Model C
...
ref Model B2
...

In EMF Editor the dependent files are loading when I spread the hierarchy.

In GMF Editor it seems that all referenced files are loaded when editor
opens. I would want that only the first references (BX in my example)
are loaded (Otherwise the opening can be very long).

How can I control the loading of depending resource in GMF ?

Hello Hugues,

AFAIR currently "total loading" of all the cross-referenced resources is
a side-effect of CrossReferenceAdapter attached to newly created ResourceSet
inside GMFEditingDomainFactory. I doubt you can simply switch to WorkspaceEditingDomainFactory
to get rid of this problem - i remember some other malfunctions were shown
up then I switched my diagram editor to WorkspaceEditingDomainFactory.

You can try submitting a request for a runtime team asking them to remove
CrossReferenceAdapter or modify it in a way not to load all the referenced
resources (use new CrossReferenceAdapter(false)) for now.

Thanks Alex for your response.

I've patched XXXDiagramEditor.createEditingDomain

Like This (Remove and recreate CrossReferenceAdapter with "false"
parameter) :

@Override
protected TransactionalEditingDomain createEditingDomain() {
TransactionalEditingDomain ted = super.createEditingDomain();
EList<Adapter> list = ted.getResourceSet().eAdapters();
Adapter adapter = null;
for (Adapter _adapter : list)
if (_adapter instanceof CrossReferenceAdapter){
adapter = _adapter;
break;
}
if (adapter != null) {
list.remove(adapter);
list.add(new CrossReferenceAdapter(false));
}
return ted;
}

But I've still all my resources loaded...

Hello Hugues,

Can you check if any resources were arleady loaded into corresponding ResrourceSet
in the moment you are removing CrossReference adapter?
Can yu just remove this adapter (comment out the line list.add(new CrossReferenceAdapter(false));)

Hi Alex,

Sorry to have delayed my answer.

> Can you check if any resources were arleady loaded into corresponding

There is no loaded resource at this moment.

> Can yu just remove this adapter (comment out the line list.add(new
> CrossReferenceAdapter(false));)

It doesn't change anything.

Have you another idea?

Thanks again,

Hugues

Hello Hugues,

> Have you another idea?
Put a breakpoint into ResourceImpl.load() method to see stack trace and determine
a reason why was it called...

Hi Alex,

I've put a breakpoint in resourceImpl.load(), and remarked than
DocumentProvider has a createEditingDomain too, I've applied the same
modification (remove and replace by CrossReferenceAdapter(false)) and
it's working fine.

Is it normal that both functions:
"XXXDocumentProvider.createEditingDomain" and
"XXXDiagramEditor.createEditingDomain"
don't use the same editing domain?

Am I right with my solution?

Thanks Alex,

Hugues.

I think second one (XXXDiagramEditor.createEditingDomain) will not be called
by generated code...

> Am I right with my solution?
Yes. You have to modify XXXDocumentProvider.createEditingDomain() to change
EditingDomain used by generated diagram editor.
