buffer - Custom FrameDecoder in netty -


i have problem framedecoder of netty following.

  • packet fragmented in {n} frames framedecoder processing correctly.
  • if many packets composed 1 frame , send server(when client sending small packet data continuously), framedecoder reads first packet. remaing ignored.

can remaining data continued executed framedecoder?

public class binaryframedecoder extends framedecoder {     @override     protected object decode(channelhandlercontext ctx, channel channel, channelbuffer buffer){         if(buffer.readablebytes() < 2){             return null;         }          int length = buffer.getshort(buffer.readerindex());         if(buffer.readablebytes() < length + 2){             return null;         }         buffer.skipbytes(2);                         return buffer;     } }

it should work if replace:

return buffer;

with:

return buffer.readbytes(length);

because buffer contains more 1 message.
