Field Summary

Fields
Modifier and Type	Field	Description
`static int`	`ABNORMAL_CLOSE`	1006 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
`static int`	`BAD_GATEWAY`	1014 indicates that the server was acting as a gateway or proxy and received an invalid response from the upstream server.
`static int`	`BUGGYCLOSE`	The connection had a buggy close (this should not happen)
`static int`	`EXTENSION`	1010 indicates that an endpoint (client) is terminating the connection because it has expected the server to negotiate one or more extension, but the server didn't return them in the response message of the WebSocket handshake.
`static int`	`FLASHPOLICY`	The connection was flushed and closed
`static int`	`GOING_AWAY`	1001 indicates that an endpoint is "going away", such as a server going down, or a browser having navigated away from a page.
`static int`	`NEVER_CONNECTED`	The connection had never been established
`static int`	`NO_UTF8`	1007 indicates that an endpoint is terminating the connection because it has received data within a message that was not consistent with the type of the message (e.g., non-UTF-8 [RFC3629] data within a text message).
`static int`	`NOCODE`	1005 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
`static int`	`NORMAL`	indicates a normal closure, meaning whatever purpose the connection was established for has been fulfilled.
`static int`	`POLICY_VALIDATION`	1008 indicates that an endpoint is terminating the connection because it has received a message that violates its policy.
`static int`	`PROTOCOL_ERROR`	1002 indicates that an endpoint is terminating the connection due to a protocol error.
`static int`	`REFUSE`	1003 indicates that an endpoint is terminating the connection because it has received a type of data it cannot accept (e.g.
`static int`	`SERVICE_RESTART`	1012 indicates that the service is restarted.
`static int`	`TLS_ERROR`	1015 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
`static int`	`TOOBIG`	1009 indicates that an endpoint is terminating the connection because it has received a message which is too big for it to process.
`static int`	`TRY_AGAIN_LATER`	1013 indicates that the service is experiencing overload.
`static int`	`UNEXPECTED_CONDITION`	1011 indicates that a server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.

- Field Detail
  - NORMAL
```
public static final int NORMAL
```
    indicates a normal closure, meaning whatever purpose the connection was established for has been fulfilled.
    
    See Also:
    
    Constant Field Values
  - GOING_AWAY
```
public static final int GOING_AWAY
```
    1001 indicates that an endpoint is "going away", such as a server going down, or a browser having navigated away from a page.
    
    See Also:
    
    Constant Field Values
  - PROTOCOL_ERROR
```
public static final int PROTOCOL_ERROR
```
    1002 indicates that an endpoint is terminating the connection due to a protocol error.
    
    See Also:
    
    Constant Field Values
  - REFUSE
```
public static final int REFUSE
```
    1003 indicates that an endpoint is terminating the connection because it has received a type of data it cannot accept (e.g. an endpoint that understands only text data MAY send this if it receives a binary message).
    
    See Also:
    
    Constant Field Values
  - NOCODE
```
public static final int NOCODE
```
    1005 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that no status code was actually present.
    
    See Also:
    
    Constant Field Values
  - ABNORMAL_CLOSE
```
public static final int ABNORMAL_CLOSE
```
    1006 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that the connection was closed abnormally, e.g. without sending or receiving a Close control frame.
    
    See Also:
    
    Constant Field Values
  - NO_UTF8
```
public static final int NO_UTF8
```
    1007 indicates that an endpoint is terminating the connection because it has received data within a message that was not consistent with the type of the message (e.g., non-UTF-8 [RFC3629] data within a text message).
    
    See Also:
    
    Constant Field Values
  - POLICY_VALIDATION
```
public static final int POLICY_VALIDATION
```
    1008 indicates that an endpoint is terminating the connection because it has received a message that violates its policy. This is a generic status code that can be returned when there is no other more suitable status code (e.g. 1003 or 1009), or if there is a need to hide specific details about the policy.
    
    See Also:
    
    Constant Field Values
  - TOOBIG
```
public static final int TOOBIG
```
    1009 indicates that an endpoint is terminating the connection because it has received a message which is too big for it to process.
    
    See Also:
    
    Constant Field Values
  - EXTENSION
```
public static final int EXTENSION
```
    1010 indicates that an endpoint (client) is terminating the connection because it has expected the server to negotiate one or more extension, but the server didn't return them in the response message of the WebSocket handshake. The list of extensions which are needed SHOULD appear in the /reason/ part of the Close frame. Note that this status code is not used by the server, because it can fail the WebSocket handshake instead.
    
    See Also:
    
    Constant Field Values
  - UNEXPECTED_CONDITION
```
public static final int UNEXPECTED_CONDITION
```
    1011 indicates that a server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.
    
    See Also:
    
    Constant Field Values
  - SERVICE_RESTART
```
public static final int SERVICE_RESTART
```
    1012 indicates that the service is restarted. A client may reconnect, and if it choses to do, should reconnect using a randomized delay of 5 - 30s. See https://www.ietf.org/mail-archive/web/hybi/current/msg09670.html for more information.
    
    Since:
    
    1.3.8
    
    See Also:
    
    Constant Field Values
  - TRY_AGAIN_LATER
```
public static final int TRY_AGAIN_LATER
```
    1013 indicates that the service is experiencing overload. A client should only connect to a different IP (when there are multiple for the target) or reconnect to the same IP upon user action. See https://www.ietf.org/mail-archive/web/hybi/current/msg09670.html for more information.

    Constant Field Values
  - BAD_GATEWAY
```
public static final int BAD_GATEWAY
```
    1014 indicates that the server was acting as a gateway or proxy and received an invalid response from the upstream server. This is similar to 502 HTTP Status Code See https://www.ietf.org/mail-archive/web/hybi/current/msg10748.html fore more information.
    
    Since:
    
    1.3.8

```
public static final int TLS_ERROR
```
    1015 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
