Class CompactJavaSerializer<T>

java.lang.Object

org.ehcache.impl.serialization.CompactJavaSerializer<T>

All Implemented Interfaces:

Serializer<T>, StatefulSerializer<T>

public class CompactJavaSerializer<T>
extends java.lang.Object
implements StatefulSerializer<T>

A trivially compressed Java serialization based serializer.

Class descriptors in the resultant bytes are encoded as integers. Mappings between the integer representation and the ObjectStreamClass, and the Class and the integer representation are stored in a single on-heap map.

Method Detail

asTypedSerializer

public static <T> java.lang.Class<? extends Serializer<T>> asTypedSerializer()

init

public void init(StateRepository stateRepository)

Description copied from interface: StatefulSerializer

This method is used to inject a StateRepository to the serializer by the authoritative tier of a cache during the cache initialization. The passed in state repository will have the persistent properties of the injecting tier.

Specified by:

init in interface StatefulSerializer<T>

Parameters:

stateRepository - the state repository

serialize

public java.nio.ByteBuffer serialize(T object)
                              throws SerializerException

Transforms the given instance into its serial form.

Specified by:

serialize in interface Serializer<T>

Parameters:

object - the instance to serialize

Returns:

the binary representation of the serial form

Throws:

SerializerException - if serialization fails

read

public T read(java.nio.ByteBuffer binary)
       throws java.lang.ClassNotFoundException,
              SerializerException

Reconstructs an instance from the given serial form.

Specified by:

read in interface Serializer<T>

Parameters:

binary - the binary representation of the serial form

Returns:

the de-serialized instance

Throws:

java.lang.ClassNotFoundException - if the type to de-serialize to cannot be found

SerializerException - if reading the byte buffer fails

equals

public boolean equals(T object,
                      java.nio.ByteBuffer binary)
               throws java.lang.ClassNotFoundException,
                      SerializerException

Checks if the given instance and serial form represent the same instance.

Specified by:

equals in interface Serializer<T>

Parameters:

object - the instance to check

binary - the serial form to check

Returns:

true if both parameters represent equal instances, false otherwise

Throws:

java.lang.ClassNotFoundException - if the type to de-serialize to cannot be found

SerializerException - if reading the byte buffer fails
