    Returns the number of transferred bytes.

  • isEndOfInput

    public boolean isEndOfInput()
     throws java.lang.Exception

    Description copied from interface: ChunkedInput
    Return true if and only if there is no data left in the stream and the stream has reached at its end.

    Specified by:

    isEndOfInput in interface ChunkedInput<ByteBuf>

    Throws:

    java.lang.Exception

  • close

    public void close()
     throws java.lang.Exception

    Description copied from interface: ChunkedInput
    Releases the resources associated with the input.

    Specified by:

    close in interface ChunkedInput<ByteBuf>

    Throws:

    java.lang.Exception

  • readChunk

    public ByteBuf readChunk(ChannelHandlerContext ctx)
     throws java.lang.Exception

    Description copied from interface: ChunkedInput
    Fetches a chunked data from the stream. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent ChunkedInput.isEndOfInput() call must return true.

    Specified by:

    readChunk in interface ChunkedInput<ByteBuf>

    Returns:

    the fetched chunk. null if there is no data left in the stream. Please note that null does not necessarily mean that the stream has reached at its end. In a slow stream, the next chunk might be unavailable just momentarily.

    Throws:

    java.lang.Exception
