Class HierarchyVisitor

java.lang.Object
  org.teiid.language.visitor.AbstractLanguageVisitor
      org.teiid.language.visitor.HierarchyVisitor

All Implemented Interfaces:

LanguageObjectVisitor

Direct Known Subclasses:

CriteriaVisitor, DelegatingHierarchyVisitor, TickerCollectorVisitor

public abstract class HierarchyVisitor
extends AbstractLanguageVisitor

Visits each node in a hierarchy of ILanguageObjects. The default implementation of each visit() method is simply to visit the children of a given ILanguageObject, 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 ILanguageObject are visited.
