  • ObjectDecoder

    public ObjectDecoder(ClassResolver classResolver)

    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.

    Parameters:

    classResolver - the ClassResolver to use for this decoder

  • ObjectDecoder

    public ObjectDecoder(int maxObjectSize,
     ClassResolver classResolver)

    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, StreamCorruptedException will be raised.

    classResolver - the ClassResolver which will load the class of the serialized object

  • decode

    protected java.lang.Object decode(ChannelHandlerContext ctx,
     ByteBuf in)
     throws java.lang.Exception

    Description copied from class: LengthFieldBasedFrameDecoder
    Create a frame out of the ByteBuf and return it.

    Overrides:

    decode in class LengthFieldBasedFrameDecoder

    Parameters:

    ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

    in - the ByteBuf from which to read data

    Returns:

    frame the ByteBuf which represent the frame or null if no frame could be created.

    Throws:

    java.lang.Exception
