BloombergLP::bdlc::CompactedArray_ConstIterator::operator‐‐

Decrement this iterator to refer to the previous location in the referenced array, and return a reference to this iterator after the decrementation. The returned iterator, it, referencing a CompactedArray array, remains valid as long as 0 <= it ‐ array.begin() <= array.length(). The behavior is undefined unless, on entry, CompactedArray_ConstIterator() != *this and 0 < *this ‐ array.begin().
