Constructor Detail

DefaultTuple.DefaultTupleRawComparator

public DefaultTuple.DefaultTupleRawComparator()
Method Detail

getConf

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

setConf

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

hasComparedTupleNull

public boolean hasComparedTupleNull()
Description copied from interface: TupleRawComparator
Checks if one of the compared tuples had a null field. This method is meaningful only when RawComparator.compare(byte[],int,int,byte[],int,int) has returned a zero value (i.e. tuples are determined to be equal).

Specified by:
hasComparedTupleNull in interface TupleRawComparator
Returns:
true if one of the compared tuples had a null field, false otherwise.

compare

public int compare(byte[] b1,
                   int s1,
                   int l1,
                   byte[] b2,
                   int s2,
                   int l2)
Compare two DefaultTuples as raw bytes. We assume the Tuples are NOT PigNullableWritable, so client classes need to deal with Null and Index.

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