public class CompatibleMarshallingDecoder extends ReplayingDecoder<VoidEnum>
ReplayingDecoder
which use an Unmarshaller
to read the Object out of the ChannelBuffer

.provider
- the UnmarshallerProvider
which is used to obtain the Unmarshaller
for the Channel
maxObjectSize
- 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
