    • 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.

      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.

      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.

      • GOING_AWAY

        public static final int GOING_AWAY

      • 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).

        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.

        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.

        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).

      • 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.

        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.

        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.

      • 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.

      • TRY_AGAIN_LATER

        public static final int TRY_AGAIN_LATER
