- Description copied from class:
WritableComparator
- Optimization hook. Override this to make SequenceFile.Sorter's scream.
The default implementation reads the data into two WritableComparable
s (using Writable.readFields(DataInput)
, then calls WritableComparator.compare(WritableComparable,WritableComparable)
.
- Specified by:
