Class DeserializerComparator<T>
java.lang.Object
org.apache.hadoop.io.serializer.DeserializerComparator<T>
- Type Parameters:
T
-
- All Implemented Interfaces:
- Comparator<T>, RawComparator<T>
- Direct Known Subclasses:
- JavaSerializationComparator
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.
