All Implemented Interfaces:

ChannelHandler, ChannelOutboundHandler

Deprecated.

This class has been deprecated with no replacement, because serialization can be a security liability

@Deprecated
public class CompatibleObjectEncoder
extends MessageToByteEncoder<Serializable>

An encoder which serializes a Java object into a ByteBuf (interoperability version).

This encoder is interoperable with the standard Java object streams such as ObjectInputStream and ObjectOutputStream.

Security: serialization can be a security liability, and should not be used without defining a list of classes that are allowed to be desirialized. Such a list can be specified with the jdk.serialFilter system property, for instance. See the serialization filtering article for more information.

Constructor Detail

CompatibleObjectEncoder

public CompatibleObjectEncoder()

Deprecated.

Creates a new instance with the reset interval of 16.

CompatibleObjectEncoder

public CompatibleObjectEncoder(int resetInterval)

Deprecated.

Creates a new instance.

Parameters:

resetInterval - the number of objects between ObjectOutputStream.reset(). 0 will disable resetting the stream, but the remote peer will be at the risk of getting OutOfMemoryError in the long term.

Method Detail

newObjectOutputStream

protected ObjectOutputStream newObjectOutputStream(OutputStream out)
                                            throws Exception

Deprecated.

Creates a new ObjectOutputStream which wraps the specified OutputStream. Override this method to use a subclass of the ObjectOutputStream.

Throws:

Exception

encode

protected void encode(ChannelHandlerContext ctx,
                      Serializable msg,
                      ByteBuf out)
               throws Exception

Deprecated.

Description copied from class: MessageToByteEncoder

Encode a message into a ByteBuf. This method will be called for each written message that can be handled by this encoder.

Specified by:

encode in class MessageToByteEncoder<Serializable>

Parameters:

ctx - the ChannelHandlerContext which this MessageToByteEncoder belongs to

msg - the message to encode

out - the ByteBuf into which the encoded message will be written

Throws:

Exception - is thrown if an error occurs
