public abstract class HierarchyVisitor
extends AbstractLanguageVisitor

Visits each node in a hierarchy of LanguageObjects. The default implementation of each visit() method is simply to visit the children of a given LanguageObject, if any exist, with this HierarchyVisitor (without performing any actions on the node). A subclass can selectively override visit() methods to delegate the actions performed on a node to another visitor by calling that Visitor's visit() method. This implementation makes no guarantees about the order in which the children of an LanguageObject are visited.
