public class SerializationProxy
extends MapProxy
implements Externalizable

This class is the server side portion of a custom serialization mechanism to support partial serialization of Objects. The client uses the Externalizable interface to guarantee the serialization order of the properties. The name of the remote class is the first property send as it is needed to construct an object shell before deserializing any of the wrapped instance properties so that object references are correctly restored.

SerializationProxy()
Default constructor required for deserialization of client SerializationProxy instances.

SerializationProxy(Object defaultInstance)

Method Summary

Object	clone() Returns a copy of the PropertyProxy so that it can be used as a template without modifying/creating global references to instances, descriptors etc.
boolean	isExternalizable() Specifies whether the default instance manages its own serialization through the Externalizable interface.
boolean	isExternalizable(Object instance) Specifies whether the given instance manages its own serialization through the Externalizable interface.
void	readExternal(ObjectInput in)
String	toString() A string including the default instance, class and descriptor info

Constructor Detail

SerializationProxy

public SerializationProxy()

Default constructor required for deserialization of client SerializationProxy instances. A SerializationProxy is merely a utility wrapper on the server side which is discarded once the externalizable information has been read and the wrapped instance constructed.

SerializationProxy

public SerializationProxy(Object defaultInstance)

Method Detail

isExternalizable

public boolean isExternalizable()

Description copied from class: AbstractProxy

Specifies whether the default instance manages its own serialization through the Externalizable interface.

Specified by:

isExternalizable in interface PropertyProxy

Overrides:

isExternalizable in class AbstractProxy

Returns:

Whether the default instance implements java.io.Externalizable.

isExternalizable

public boolean isExternalizable(Object instance)

Description copied from class: AbstractProxy

Specifies whether the given instance manages its own serialization through the Externalizable interface.

Specified by:

isExternalizable in interface PropertyProxy

Overrides:

isExternalizable in class AbstractProxy

Parameters:

instance - the object to check

Returns:

Whether the given instance implements java.io.Externalizable.

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

toString

public String toString()

Description copied from class: AbstractProxy

A string including the default instance, class and descriptor info

Overrides:

toString in class AbstractProxy

Returns:

debug string.

clone

public Object clone()

Returns a copy of the PropertyProxy so that it can be used as a template without modifying/creating global references to instances, descriptors etc.

Specified by:

clone in interface PropertyProxy

Overrides:

clone in class MapProxy

Returns:

A copy of the PropertyProxy.
