Constructor Detail

PigBytesRawComparator

public PigBytesRawComparator()
Method Detail

setConf

public void setConf(org.apache.hadoop.conf.Configuration conf)
Specified by:
setConf in interface org.apache.hadoop.conf.Configurable

getConf

public org.apache.hadoop.conf.Configuration getConf()
Specified by:
getConf in interface org.apache.hadoop.conf.Configurable

compare

public int compare(byte[] b1,
                   int s1,
                   int l1,
                   byte[] b2,
                   int s2,
                   int l2)
Compare two NullableBytesWritables as raw bytes. If both are null, then the indices are compared. If neither are null and both are bytearrays, then direct Writable.compareBytes is used. For non-bytearrays, we use BinInterSedesTupleRawComparator. If either is null, null one is defined to be less.

Specified by:
compare in interface org.apache.hadoop.io.RawComparator
Overrides:
compare in class org.apache.hadoop.io.WritableComparator

compare

public int compare(Object o1,
                   Object o2)
