Interface SerializationProvider

public interface SerializationProvider

This interface provides a mechanism to allow the use of alternate Java Serialization implementations.

The implementation of this interface *must* be thread-safe and must have a no-arg constructor.

Method Summary

Modifier and Type	Method and Description
ObjectInputStream	createObjectInputStream(InputStream source) Creates a new ObjectInputStream wrapping the specified source.
ObjectOutputStream	createObjectOutputStream(OutputStream destination) Creates a new ObjectOutputStream wrapping the specified destination.

Method Detail

createObjectInputStream

ObjectInputStream createObjectInputStream(InputStream source)
                                   throws IOException

Creates a new ObjectInputStream wrapping the specified source.

It's extremely important that the ObjectInputStream returned by this method extends the serialization implementation's ObjectInputStream and overrides the ObjectInputStream.resolveClass(java.io.ObjectStreamClass) of to perform the following or the equivalent thereof:

 return Class.forName(desc.getName(), true, Thread.currentThread().getContextClassLoader());
 

If this step isn't done, there may be problems when deserializing.

Parameters:

source - the source stream from which to read the Object(s) from

Returns:

an ObjectInputStream

Throws:

IOException - if an error occurs when creating the input stream

createObjectOutputStream

ObjectOutputStream createObjectOutputStream(OutputStream destination)
                                     throws IOException

Creates a new ObjectOutputStream wrapping the specified destination.

Parameters:

destination - the destination of the serialized Object(s)

Returns:

an ObjectOutputStream

Throws:

IOException - if an error occurs when creating the output stream
