- Method Detail
  - canSuspendReceiving
```
protected boolean canSuspendReceiving()
```
    Description copied from class: AbstractListenerWebSocketSession
    Whether the underlying WebSocket API has flow control and can suspend and resume the receiving of messages.
    Note: Sub-classes are encouraged to start out in suspended mode, if possible, and wait until demand is received.
    Specified by:
    canSuspendReceiving in class AbstractListenerWebSocketSession<io.undertow.websockets.core.WebSocketChannel>
  - suspendReceiving
```
protected void suspendReceiving()
```
    Description copied from class: AbstractListenerWebSocketSession
    Suspend receiving until received message(s) are processed and more demand is generated by the downstream Subscriber.
    Note: if the underlying WebSocket API does not provide flow control for receiving messages, this method should be a no-op and AbstractListenerWebSocketSession.canSuspendReceiving() should return false.
    Specified by:
    suspendReceiving in class AbstractListenerWebSocketSession<io.undertow.websockets.core.WebSocketChannel>
  - resumeReceiving
```
protected void resumeReceiving()
```
    Description copied from class: AbstractListenerWebSocketSession
    Resume receiving new message(s) after demand is generated by the downstream Subscriber.
    Note: if the underlying WebSocket API does not provide flow control for receiving messages, this method should be a no-op and AbstractListenerWebSocketSession.canSuspendReceiving() should return false.
    Specified by:
    resumeReceiving in class AbstractListenerWebSocketSession<io.undertow.websockets.core.WebSocketChannel>
  - sendMessage
```
protected boolean sendMessage(WebSocketMessage message)
                       throws IOException
```
    Description copied from class: AbstractListenerWebSocketSession
    Send the given WebSocket message.
    Note: Sub-classes are responsible for releasing the payload data buffer, once fully written, if pooled buffers apply to the underlying container.
    Specified by:
    sendMessage in class AbstractListenerWebSocketSession<io.undertow.websockets.core.WebSocketChannel>
    Throws:
    IOException
  - close
```
public reactor.core.publisher.Mono<Void> close(CloseStatus status)
```
    Description copied from interface: WebSocketSession
    Close the WebSocket session with the given status.
    Parameters:
    status - the close status
