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)

preOrder

public boolean preOrder()

Returns:

if objects should be visited before their outgoing edges

visitProxyReference
