- @InterfaceAudience.LimitedPrivate(value={"HDFS","MapReduce"}) @InterfaceStability.Evolving public abstract class DeserializerComparator<T> extends Object implements RawComparator<T>
A RawComparator
that uses a Deserializer
to deserialize
the objects to be compared so that the standard Comparator
can
be used to compare them.
One may optimize compare-intensive operations by using a custom
implementation of RawComparator
that operates directly
on byte representations.

b1
- The first byte array.s1
- The position index in b1. The object under comparison's starting index.l1
- The length of the object in b1.b2
- The second byte array.s2
- The position index in b2. The object under comparison's starting index.l2
- The length of the object under comparison in b2.Copyright © 2013 Apache Software Foundation. All rights reserved.
