 *
 * 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.
 *
 * To iterate over code points and strings, use a loop like this:
 * <pre>
 * UnicodeSetIterator it(set);
 * while (it.next()) {
 * processItem(it.getString());
 * }
 * </pre>
 * 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.
 *
 * 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());
 * }
 * }
