  - ### doRead

    public int doRead(ApplicationBufferHandler handler) throws IOException
    Description copied from interface: `InputBuffer`
    Read from the input stream into the ByteBuffer provided by the ApplicationBufferHandler. IMPORTANT: the current model assumes that the protocol will 'own' the ByteBuffer and return a pointer to it.
    Specified by:
      `doRead` in interface `InputBuffer`
    Parameters:
      `handler` - ApplicationBufferHandler that provides the buffer to read data into.
    Returns:
      The number of bytes that have been added to the buffer or -1 for end of stream
    Throws:
      `IOException` - If an I/O error occurs reading from the input stream

  - ### available

    public int available()
    Description copied from interface: `InputBuffer`
    Obtain an estimate of the number of bytes that can be read without blocking. Typically, this will be the number of available bytes known to be buffered.
    Specified by:
      `available` in interface `InputBuffer`
    Returns:
      The number of bytes that can be read without blocking
