类 DeserializerComparator<T>

java.lang.Object

org.apache.hadoop.io.serializer.DeserializerComparator<T>

类型参数:

T -

所有已实现的接口:

Comparator<T>, RawComparator<T>

直接已知子类:

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.
