java.lang.Object
- org.springframework.web.socket.handler.WebSocketHandlerDecorator

所有已实现的接口:
WebSocketHandler
直接已知子类:
ExceptionWebSocketHandlerDecorator, LoggingWebSocketHandlerDecorator
```
public class WebSocketHandlerDecorator
extends Object
implements WebSocketHandler
```
Wraps another WebSocketHandler instance and delegates to it.
Also provides a getDelegate() method to return the decorated handler as well as a getLastHandler() method to go through all nested delegates and return the "last" handler.
从以下版本开始:
4.0

    Invoked after WebSocket negotiation has succeeded and the WebSocket connection is opened and ready for use.
    指定者:
    afterConnectionEstablished 在接口中 WebSocketHandler
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - handleMessage
```
public void handleMessage(WebSocketSession session,
                          WebSocketMessage<?> message)
                   throws Exception
```

    Invoked when a new WebSocket message arrives.
    指定者:
    handleMessage 在接口中 WebSocketHandler
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - handleTransportError
```
public void handleTransportError(WebSocketSession session,

                          throws Exception
```
    从接口复制的说明: WebSocketHandler
    Handle an error from the underlying WebSocket message transport.
    指定者:
    handleTransportError 在接口中 WebSocketHandler
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - afterConnectionClosed
```
public void afterConnectionClosed(WebSocketSession session,
                                  CloseStatus closeStatus)
                           throws Exception
```
    从接口复制的说明: WebSocketHandler
    Invoked after the WebSocket connection has been closed by either side, or after a transport error has occurred. Although the session may technically still be open, depending on the underlying implementation, sending messages at this point is discouraged and most likely will not succeed.
    指定者:
    afterConnectionClosed 在接口中 WebSocketHandler
    抛出:
    Exception - this method can handle or propagate exceptions; see class-level Javadoc for details.
  - supportsPartialMessages
```
public boolean supportsPartialMessages()
```
    从接口复制的说明: WebSocketHandler
    Whether the WebSocketHandler handles partial messages. If this flag is set to true and the underlying WebSocket server supports partial messages, then a large WebSocket message, or one of an unknown size may be split and maybe received over multiple calls to WebSocketHandler.handleMessage(WebSocketSession, WebSocketMessage). The flag WebSocketMessage.isLast() indicates if the message is partial and whether it is the last part.
    指定者:
    supportsPartialMessages 在接口中 WebSocketHandler
  - toString
```
public String toString()
```
    覆盖:
    toString 在类中 Object
