org.apache.hadoop.hbase.util.Order
@InterfaceAudience.Public @InterfaceStability.Evolving public enum Order
Used to describe or modify the lexicographical sort order of a
byte[]. Default ordering is considered ASCENDING. The order
of a byte[] can be inverted, resulting in DESCENDING order,
by replacing each byte with its 1's compliment.
