Class RecursiveCharIterator

  • All Implemented Interfaces:
    java.lang.Cloneable, java.util.Iterator

    public class RecursiveCharIterator
    extends CharIterator
    Kind of a super-iterator that iterates through child nodes of an FONode, in turn managing character iterators for each of them. Caveat: Because this class is itself a CharIterator, and manages a collection of CharIterators, it is easy to get confused.
