Constructor Detail

MarshallingDecoder

public MarshallingDecoder(UnmarshallerProvider provider)

Creates a new decoder whose maximum object size is 1048576 bytes. If the size of the received object is greater than 1048576 bytes, a StreamCorruptedException will be raised.

MarshallingDecoder

public MarshallingDecoder(UnmarshallerProvider provider,
                          int maxObjectSize)

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, TooLongFrameException will be raised.

Method Detail

decode

protected Object decode(io.netty.channel.ChannelHandlerContext ctx,
                        io.netty.buffer.ByteBuf in)
                 throws Exception

Overrides:

decode in class io.netty.handler.codec.LengthFieldBasedFrameDecoder

Throws:

Exception

extractFrame

protected io.netty.buffer.ByteBuf extractFrame(io.netty.channel.ChannelHandlerContext ctx,
                                               io.netty.buffer.ByteBuf buffer,
                                               int index,
                                               int length)

Overrides:

extractFrame in class io.netty.handler.codec.LengthFieldBasedFrameDecoder
