How to use

remaining

method

in

org.eclipse.jetty.http2.frames.DataFrame

private DataEntry(DataFrame frame, IStream stream, Callback callback)
{
  super(frame, stream, callback);
  // We don't do any padding, so the flow control length is
  // always the data remaining. This simplifies the handling
  // of data frames that cannot be completely written due to
  // the flow control window exhausting, since in that case
  // we would have to count the padding only once.
  dataRemaining = frame.remaining();
}
