Hi,

for index performance reasons, IncQuery current does not support referencing the containment hierarchy directly, however, if you know which features to check, there is a workaround for that: you can have a pattern that provides the union of all features. For example, see the following helper pattern:

pattern container(EObject container, EObject object) {
  Class.ownedOperation(container, object);
} or {
  StructuredClassifier.ownedAttributes(container, object);
} or {
  //You have to have a body for all interesting containment references
 ...
}

Hi Van Cam,

I think you might find that EObject#eContainer(), combined with EObject#eContainingFeature() or EObject#eContainmentFeature(), will do what you want for EObject values.

Hi Gabor, I've tried this but it does not work.
