Method Details

onPreface

public Map<Integer,Integer> onPreface(Session session)

Description copied from interface: Session.Listener

Callback method invoked:

• for clients, just before the preface is sent, to gather the SETTINGS configuration options the client wants to send to the server;
• for servers, just after having received the preface, to gather the SETTINGS configuration options the server wants to send to the client.

Specified by:

onPreface in interface Session.Listener

Parameters:

session - the session

Returns:

a (possibly empty or null) map containing SETTINGS configuration options to send.

onNewStream

public Stream.Listener onNewStream(Stream stream,
 HeadersFrame frame)

Description copied from interface: Session.Listener

Callback method invoked when a new stream is being created upon receiving a HEADERS frame representing an HTTP request.

Applications should implement this method to process HTTP requests, typically providing an HTTP response via Stream.headers(HeadersFrame, Callback).

Applications can detect whether request DATA frames will be arriving by testing HeadersFrame.isEndStream(). If the application is interested in processing the DATA frames, it must return a Stream.Listener implementation that overrides Stream.Listener.onData(Stream, DataFrame, Callback).

Specified by:

onNewStream in interface Session.Listener

Parameters:

stream - the newly created stream

frame - the HEADERS frame received

Returns:

a Stream.Listener that will be notified of stream events

onSettings

public void onSettings(Session session,
 SettingsFrame frame)

Description copied from interface: Session.Listener

Callback method invoked when a SETTINGS frame has been received.

Specified by:

onSettings in interface Session.Listener

Parameters:

session - the session

frame - the SETTINGS frame received

onPing

public void onPing(Session session,
 PingFrame frame)

Description copied from interface: Session.Listener

Callback method invoked when a PING frame has been received.

Specified by:

onPing in interface Session.Listener

Parameters:

session - the session

frame - the PING frame received

onReset

public void onReset(Session session,
 ResetFrame frame)

Description copied from interface: Session.Listener

Callback method invoked when a RST_STREAM frame has been received for an unknown stream.

Specified by:

onReset in interface Session.Listener

Parameters:

session - the session

frame - the RST_STREAM frame received

See Also:

• Stream.Listener.onReset(Stream, ResetFrame)

onClose

public void onClose(Session session,
 GoAwayFrame frame)

Specified by:

onClose in interface Session.Listener

onIdleTimeout

public boolean onIdleTimeout(Session session)

Description copied from interface: Session.Listener

Callback method invoked when the idle timeout expired.

Specified by:

onIdleTimeout in interface Session.Listener

Parameters:

session - the session

Returns:

whether the session should be closed

onFailure

public void onFailure(Session session,
 Throwable failure)

Specified by:

onFailure in interface Session.Listener
