public class ElementOwnerMatcher extends org.eclipse.viatra.query.runtime.api.impl.BaseMatcher<ElementOwnerMatch>
Use the pattern matcher on a given model via on(ViatraQueryEngine)
,
e.g. in conjunction with ViatraQueryEngine#on(Notifier)
.
Matches of the pattern will be represented as ElementOwnerMatch
.
Original source:
@Surrogate(feature = "owner")
@QueryExplorer(checked = false)
pattern elementOwner(source: Element, target: Element){
// opposite of Element.ownedElement
find elementOwnedElement(target, source);
}
