WebSocketExtension (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- org.springframework.web.socket.WebSocketExtension

直接已知子类:
StandardToWebSocketExtensionAdapter
```
public class WebSocketExtension
extends Object
```
Represents a WebSocket extension as defined in the RFC 6455. WebSocket extensions add protocol features to the WebSocket protocol. The extensions used within a session are negotiated during the handshake phase as follows:
- the client may ask for specific extensions in the HTTP handshake request
- the server responds with the final list of extensions to use in the current session
WebSocket Extension HTTP headers may include parameters and follow RFC 7230 section 3.2
Note that the order of extensions in HTTP headers defines their order of execution, e.g. extensions "foo, bar" will be executed as "bar(foo(message))".
