All Implemented Interfaces:

Closeable, DataInput, ObjectInput, ObjectStreamConstants, AutoCloseable

public class ProxyObjectInputStream
extends ObjectInputStream

An input stream class which knows how to deserialize proxies created via ProxyFactory and serializedo via a ProxyObjectOutputStream. It must be used when deserialising proxies created from a proxy factory configured with ProxyFactory.useWriteReplace set to false.

Field Details

loader

private ClassLoader loader

the loader to use to resolve classes for proxy superclass and interface names read from the stream. defaults to the context class loader of the thread which creates the input stream or the system class loader if the context class loader is null.

Constructor Details

ProxyObjectInputStream

public ProxyObjectInputStream(InputStream in)
                       throws IOException

create an input stream which can be used to deserialize an object graph which includes proxies created using class ProxyFactory. the classloader used to resolve proxy superclass and interface names read from the input stream will default to the current thread's context class loader or the system classloader if the context class loader is null.

Parameters:

in -

Throws:

StreamCorruptedException - whenever ObjectInputStream would also do so

IOException - whenever ObjectInputStream would also do so

SecurityException - whenever ObjectInputStream would also do so

NullPointerException - if in is null
