org.eclipse.emf.ecore.util.EcoreUtil.CrossReferencer
public static class EcoreUtil.CrossReferencer
A mapping building traverser of a collection of content trees;
the map is from target object to a collection of EStructuralFeature.Setting.
Since this implementation extends a Map implementation, it can yield itself as the result for most operations.
The traverser considers each EObject in the EObject.eCrossReferences() of each EObject in the content tree,
and creates a setting for each positive match.
This default implementation creates a map of all cross references.
