public int compare(byte[] b1,
                   int s1,

Description copied from class: WritableComparator

Optimization hook. Override this to make SequenceFile.Sorter's scream.

The default implementation reads the data into two WritableComparables (using Writable.readFields(DataInput), then calls WritableComparator.compare(WritableComparable,WritableComparable).

Specified by:

compare in interface RawComparator

Overrides:

compare in class WritableComparator
