Description

Interface Summary

Deserializer<T>	Provides a facility for deserializing objects of type from an InputStream.
Serialization<T>	Encapsulates a Serializer/Deserializer pair.
Serializer<T>	Provides a facility for serializing objects of type to an OutputStream.

Class Summary

DeserializerComparator<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.
JavaSerialization	An experimental Serialization for Java Serializable classes.
JavaSerializationComparator<T extends Serializable & Comparable<T>>	A RawComparator that uses a JavaSerialization Deserializer to deserialize objects that are then compared via their Comparable interfaces.
SerializationFactory	A factory for Serializations.
WritableSerialization	A Serialization for Writables that delegates to Writable.write(java.io.DataOutput) and Writable.readFields(java.io.DataInput).

Package org.apache.hadoop.io.serializer Description

This package provides a mechanism for using different serialization frameworks in Hadoop. The property "io.serializations" defines a list of Serializations that know how to create Serializers and Deserializers.

To add a new serialization framework write an implementation of Serialization and add its name to the "io.serializations" property.
