public CompatibleMarshallingDecoder(UnmarshallerProvider provider, int maxObjectSize)
CompatibleMarshallingDecoder.provider - the UnmarshallerProvider which is used to obtain the Unmarshaller
for the ChannelmaxObjectSize - the maximal size (in bytes) of the Object to unmarshal. Once the size is
exceeded the Channel will get closed. Use a a maxObjectSize of
Integer.MAX_VALUE to disable this. You should only do this if you are sure
that the received Objects will never be big and the sending side are trusted, as
this opens the possibility for a DOS-Attack due an OutOfMemoryError.protected Object decode(ChannelHandlerContext ctx, Channel channel, ChannelBuffer buffer, VoidEnum state) throws Exception
