DefaultWebSocketSession

Flush all outstanding messages and suspend until all earlier sent messages will be written. Could be called at any time even after close. May return immediately if the connection is already terminated. However it may also fail with an exception (or cancellation) at any point due to session failure. Please note that flush doesn't guarantee that frames were actually delivered.

Enqueue frame, may suspend if outgoing queue is full. May throw an exception if outgoing channel is already closed so it is impossible to transfer any message. Frames that were sent after close frame could be silently ignored. Please note that close frame could be sent automatically in reply to a peer close frame unless it is raw websocket session.

Start WebSocket conversation.

Initiate connection termination immediately. Termination may complete asynchronously.

A close reason for this session. It could be null if a session is terminated with no close reason (for example due to connection failure).

Negotiated WebSocket extensions.

Incoming frames channel

Enable or disable masking output messages by a random xor mask. Please note that changing this flag on the fly could be applied to the messages already sent (enqueued earlier) as the sending pipeline works asynchronously

Specifies frame size limit. Connection will be closed if violated

Outgoing frames channel. It could have limited capacity so sending too much frames may lead to suspension at corresponding send invocations. It also may suspend if a peer doesn't read frames for some reason.

Ping interval or -1L to disable pinger. Please note that pongs will be handled despite this setting.

A timeout to wait for pong reply to ping otherwise the session will be terminated immediately. It doesn't have any effect if pingIntervalMillis is -1 (pinger is disabled).
