BloombergLP::bdlc::PackedIntArrayConstIterator::operator++

Advance this iterator to refer to the next element in the referenced array and return a reference to this iterator after the advancement. The returned iterator, it, referencing an element within a PackedIntArray, array, remains valid as long as 0 <= it ‐ array.begin() <= array.length(). The behavior is undefined unless, on entry, PackedIntArrayConstInterator() != *this and *this ‐ array.begin() < array.length().
