public abstract class AbstractClientSockJsSession extends Object implements WebSocketSession
WebSocketSession.
Provides processing of incoming SockJS message frames and delegates lifecycle
events and messages to the (application) WebSocketHandler.

WebSocketSessionOn the server side the map can be populated initially through a
HandshakeInterceptor. On the client side the map can be populated via
WebSocketClient handshake methods.

public final void sendMessage(WebSocketMessage<?> message) throws IOException
WebSocketSessionTextMessage or BinaryMessage.
Note: The underlying standard WebSocket session (JSR-356) does
not allow concurrent sending. Therefore sending must be synchronized. To ensure
that, one option is to wrap the WebSocketSession with the
ConcurrentWebSocketSessionDecorator.
