Interface AbstractServerStream.Sink

Enclosing class:

AbstractServerStream

protected static interface AbstractServerStream.Sink

A sink for outbound operations, separated from the stream simply to avoid name collisions/confusion. Only called from application thread.

Method Summary

Modifier and Type	Method and Description
void	cancel(Status status) Tears down the stream, typically in the event of a timeout.
void	request(int numMessages) Requests up to the given number of messages from the call to be delivered.
void	writeFrame(WritableBuffer frame, boolean flush, int numMessages) Sends an outbound frame to the remote end point.
void	writeHeaders(Metadata headers) Sends response headers to the remote end point.
void	writeTrailers(Metadata trailers, boolean headersSent, Status status) Sends trailers to the remote end point.

Method Detail

writeHeaders

void writeHeaders(Metadata headers)

Sends response headers to the remote end point.

Parameters:

headers - the headers to be sent to client.

writeFrame

void writeFrame(@Nullable
                WritableBuffer frame,
                boolean flush,
                int numMessages)

Sends an outbound frame to the remote end point.

Parameters:

frame - a buffer containing the chunk of data to be sent.

flush - true if more data may not be arriving soon

numMessages - the number of messages this frame represents

writeTrailers

void writeTrailers(Metadata trailers,
                   boolean headersSent,
                   Status status)

Sends trailers to the remote end point. This call implies end of stream.

Parameters:

trailers - metadata to be sent to the end point

headersSent - true if response headers have already been sent.

status - the status that the call ended with

request

void request(int numMessages)

Requests up to the given number of messages from the call to be delivered. This should end up triggering AbstractStream.TransportState.requestMessagesFromDeframer(int) on the transport thread.

cancel

void cancel(Status status)

Tears down the stream, typically in the event of a timeout. This method may be called multiple times and from any thread.

This is a clone of ServerStream.cancel(Status).
