BloombergLP::bdlc::operator++

Advance the specified iterator iter to refer to the next element in the referenced array, and return an iterator referring to the original element (before 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() != iter and iter ‐ array.begin() < array.length().
