java.lang.Object

com.helger.commons.tree.util.TreeVisitor

@Immutable
public final class TreeVisitor
extends Object

A specialized walker that iterates all elements in a tree and calls a callback method. Compared to TreeWalker the callbacks used in this class allow to stop iteration or to skip all siblings.
