Date Tue, 12 Jan 2016 14:36:39 GMT

Github user twalthr commented on the pull request:

    Sorry, I mixed up atomic and basic types. I forgot that a flat comparators list could
also contain GenericTypes etc.
    Can we assume that the orders of the flat comparators returned by the `wrappedComparator`
are equal to the orders of the `wrappedComparator` itself?

> To store/materialize NULL value in Row objects, we should need new Row Serializer/Comparator
which is aware of NULL value fields.
