Constructor Detail

Http2ClientStreamTransportState

protected Http2ClientStreamTransportState(int maxMessageSize,
                                          StatsTraceContext statsTraceCtx,
                                          TransportTracer transportTracer)

Method Detail

http2ProcessingFailed

protected abstract void http2ProcessingFailed(io.grpc.Status status,
                                              boolean stopDelivery,
                                              io.grpc.Metadata trailers)

Called to process a failure in HTTP/2 processing. It should notify the transport to cancel the stream and call transportReportStatus().

transportHeadersReceived

protected void transportHeadersReceived(io.grpc.Metadata headers)

Called by subclasses whenever Headers are received from the transport.

Parameters:

headers - the received headers

transportDataReceived

protected void transportDataReceived(ReadableBuffer frame,
                                     boolean endOfStream)

Called by subclasses whenever a data frame is received from the transport.

Parameters:

frame - the received data frame

endOfStream - true if there will be no more data received for this stream

transportTrailersReceived

protected void transportTrailersReceived(io.grpc.Metadata trailers)

Called by subclasses for the terminal trailer metadata on a stream.

Parameters:

trailers - the received terminal trailer metadata

runOnTransportThread

public void runOnTransportThread(Runnable r)
