      Modifier and Type Method Description
      boolean attemptProxyResolutions​(org.eclipse.emf.ecore.EObject source, org.eclipse.emf.ecore.EReference feature)
      Whether the given reference of the given object should be resolved when it is a proxy

                                                 org.eclipse.emf.ecore.EReference feature,

                                   java.lang.Object target)
        Parameters:
        source -
        feature -
        target -
      • pruneFeature

        public boolean pruneFeature​(org.eclipse.emf.ecore.EStructuralFeature feature)
        Returns true if the given feature should not be traversed (interesting esp. if multi-valued)
      • pruneSubtrees

        public boolean pruneSubtrees​(org.eclipse.emf.ecore.EObject source)
        Returns true if the contents of an object should be pruned (and not explored by the visitor)
      • pruneSubtrees

        public boolean pruneSubtrees​(org.eclipse.emf.ecore.resource.Resource source)
        Returns true if the contents of a resource should be pruned (and not explored by the visitor)
      • avoidTransientContainmentLink

        public boolean avoidTransientContainmentLink​(org.eclipse.emf.ecore.EObject source,
                                                     org.eclipse.emf.ecore.EReference reference,
                                                     org.eclipse.emf.ecore.EObject targetObject)
        An opportunity for the visitor to indicate that the containment link is considered in a transient state, and the model comprehension should avoid following it. A containment is in a transient state from the point of view of the visitor if it connects a subtree that is being inserted during a full-model traversal, and a separate notification handler will deal with it later.
      • preOrder

        public boolean preOrder()
        Returns:
        if objects should be visited before their outgoing edges
      • visitProxyReference

        public void visitProxyReference​(org.eclipse.emf.ecore.EObject source,
                                        org.eclipse.emf.ecore.EReference reference,
                                        org.eclipse.emf.ecore.EObject targetObject,
                                        java.lang.Integer position)
        Called after visiting the reference, if the target is a proxy.
        Parameters:
        position - optional: known position in multivalued collection (for more efficient proxy resolution)
      • attemptProxyResolutions

        public boolean attemptProxyResolutions​(org.eclipse.emf.ecore.EObject source,
                                               org.eclipse.emf.ecore.EReference feature)
        Whether the given reference of the given object should be resolved when it is a proxy
      • descendAlongCrossResourceContainments

        public boolean descendAlongCrossResourceContainments()
        Returns:
        true if traversing visitors shall descend along cross-resource containments (this only makes sense for traversing visitors on an object scope)
