Method Detail

onSyn

public StreamFrameListener onSyn(Stream stream,
                        SynInfo synInfo)

Description copied from interface: SessionFrameListener

Callback invoked when a request to create a stream has been received.

Application code should implement this method and reply to the stream creation, eventually sending data:

 public Stream.FrameListener onSyn(Stream stream, SynInfo synInfo)
 {
     // Do something with the metadata contained in synInfo

     if (stream.isHalfClosed()) // The other peer will not send data
     {
         stream.reply(new ReplyInfo(false));
         stream.data(new StringDataInfo("foo", true));
         return null; // Not interested in further stream events
     }

     ...
 }
 

Alternatively, if the stream creation requires reading data sent from the other peer:

 public Stream.FrameListener onSyn(Stream stream, SynInfo synInfo)
 {
     // Do something with the metadata contained in synInfo

     if (!stream.isHalfClosed()) // The other peer will send data
     {
         stream.reply(new ReplyInfo(true));
         return new Stream.FrameListener.Adapter() // Interested in stream events
         {
             public void onData(Stream stream, DataInfo dataInfo)
             {
                 // Do something with the incoming data in dataInfo
             }
         };
     }

     ...
 }
 

Specified by:

onSyn in interface SessionFrameListener

Parameters:

stream - the stream just created

synInfo - the metadata sent on stream creation

Returns:

a listener for stream events, or null if there is no interest in being notified of stream events

onRst

public void onRst(Session session,
         RstInfo rstInfo)

Description copied from interface: SessionFrameListener

Callback invoked when a stream error happens.

Specified by:

onRst in interface SessionFrameListener

Parameters:

session - the session

rstInfo - the metadata of the stream error

onSettings

public void onSettings(Session session,
              SettingsInfo settingsInfo)

Description copied from interface: SessionFrameListener

Callback invoked when a request to configure the SPDY connection has been received.

Specified by:

onSettings in interface SessionFrameListener

Parameters:

session - the session

settingsInfo - the metadata sent to configure

onPing

public void onPing(Session session,
          PingInfo pingInfo)

Description copied from interface: SessionFrameListener

Callback invoked when a ping request has completed its round-trip.

Specified by:

onPing in interface SessionFrameListener

Parameters:

session - the session

pingInfo - the metadata received

onGoAway

public void onGoAway(Session session,
            GoAwayInfo goAwayInfo)

Description copied from interface: SessionFrameListener

Callback invoked when the other peer signals that it is closing the connection.

Specified by:

onGoAway in interface SessionFrameListener

Parameters:

session - the session

goAwayInfo - the metadata sent

onException

public void onException(Throwable x)

Description copied from interface: SessionFrameListener

Callback invoked when an exception is thrown during the processing of an event on a SPDY session.

Examples of such conditions are invalid frames received, corrupted headers compression state, etc.

Specified by:

onException in interface SessionFrameListener

Parameters:

x - the exception that caused the event processing failure
