Description copied from class: PigDoubleRawComparator

Compare two NullableIntWritables as raw bytes. If neither are null, then IntWritable.compare() is used. If both are null then the indices are compared. Otherwise the null one is defined to be less.

compare in interface org.apache.hadoop.io.RawComparator
