Objects of this class can be instantiated with IntlBreakIterator::createCodePointInstance() The method does not take a locale, as it would not make sense in this context. This class has one additional method: long IntlCodePointIterator::getLastCodePoint() which returns either -1 or the last code point we moved over, if any (and discounting any movement before the last call to IntlBreakIterator::first() or IntlBreakIterator::last()).
