-/**
- *
- * UnicodeSetIterator iterates over the contents of a UnicodeSet.  It
- * iterates over either code points or code point ranges.  After all
- * code points or ranges have been returned, it returns the
- * multicharacter strings of the UnicodeSet, if any.
- *
- * This class is not intended to be subclassed.  Consider any fields
- *  or methods declared as "protected" to be private.  The use of
- *  protected in this class is an artifact of history.
- *
- * <p>To iterate over code points and strings, use a loop like this:
- * <pre>
- * UnicodeSetIterator it(set);
- * while (it.next()) {
- *     processItem(it.getString());
- * }
- * </pre>
- * <p>Each item in the set is accessed as a string.  Set elements
- *    consisting of single code points are returned as strings containing
- *    just the one code point.
- *
- * <p>To iterate over code point ranges, instead of individual code points,
- *    use a loop like this:
- * <pre>
- * UnicodeSetIterator it(set);
- * while (it.nextRange()) {
- *   if (it.isString()) {
- *     processString(it.getString());
- *   } else {
- *     processCodepointRange(it.getCodepoint(), it.getCodepointEnd());
- *   }
- * }
- * </pre>
