- Description copied from interface:
Configurable
- Set the configuration to be used by this object.
- Specified by:
setConf
in interface Configurable
getConf
public Configuration getConf()
- Description copied from interface:
Configurable
- Return the configuration used by this object.

compare
public int compare(byte[] b1,
int s1,
int l1,
byte[] b2,
int s2,
int l2)
- 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)
.
- Overrides:
compare
