          org.jboss.invocation.pooled.interfaces.OptimizedObjectOutputStream

All Implemented Interfaces:: DataOutput, ObjectOutput, ObjectStreamConstants

public class OptimizedObjectOutputStream
extends ObjectOutputStream

An ObjectOutputStream subclass used by the MarshalledValue class to ensure the classes and proxies are loaded using the thread context class loader. Currently this does not do anything as neither class or proxy annotations are used.

Constructor Summary

OptimizedObjectOutputStream(OutputStream os)
          Creates a new instance of MarshalledValueOutputStream If there is a security manager installed, this method requires a SerializablePermission("enableSubstitution") permission to ensure it's ok to enable the stream to do replacement of objects in the stream.

Method Summary

protected Object replaceObject(Object obj)
          Override replaceObject to check for Remote objects that are not RemoteStubs.

protected void writeClassDescriptor(ObjectStreamClass classdesc)
          Writes just the class name to this output stream.
