Class ObjectDecoder

java.lang.Object
  org.jboss.netty.channel.SimpleChannelUpstreamHandler
      org.jboss.netty.handler.codec.frame.FrameDecoder
          org.teiid.transport.ObjectDecoder

All Implemented Interfaces:

org.jboss.netty.channel.ChannelHandler, org.jboss.netty.channel.ChannelUpstreamHandler

public class ObjectDecoder
extends org.jboss.netty.handler.codec.frame.FrameDecoder

A decoder which deserializes the received ChannelBuffers into Java objects.

Please note that the serialized form this decoder expects is not compatible with the standard ObjectOutputStream. Please use ObjectEncoder or ObjectEncoderOutputStream to ensure the interoperability with this decoder.

Unless there's a requirement for the interoperability with the standard object streams, it is recommended to use ObjectEncoder and ObjectDecoder rather than CompatibleObjectEncoder and CompatibleObjectDecoder.

ObjectDecoder

public ObjectDecoder(int maxObjectSize,
                     java.lang.ClassLoader classLoader,
                     StorageManager storageManager)

Creates a new decoder with the specified maximum object size.

Parameters:

maxObjectSize - the maximum byte length of the serialized object. if the length of the received object is greater than this value, StreamCorruptedException will be raised.

classLoader - the ClassLoader which will load the class of the serialized object
