-/**
- *
- * 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>
