[news.eclipse.tools.emf] Direct Reference CrossReferencer?

[Alberto Ricart <aricart@xxxxxxxxx>]

Hello,


I am wondering if there's a way to determine if a reference is direct 
or indirect.
Example if I have 3 objects, A which references B, which references C:

A->B->C


If I use any of the CrossReferencers to get the references held by A, I 
will not only get B but also C. In the case that I am looking 
(implementing a builder and refactoring), I would like to obtain only 
direct references, so A will report 'B' as its only reference and 'B' 
will report 'C' as its only reference.

Is there a way of doing this, I naively to filter things based on the 
source's uri, but that doesn't seem to do the trick.

protected boolean crossReference(EObject object, EReference reference,
			EObject crossReferencedEObject)
{
	boolean isInternal = me.equals(object.eResource().getURI());
	return isInternal;
}

protected boolean resolve()
{
   	return false;
}

Any help appreciated.

Thanks,

/a
