Enum Constant Summary

Enum Constants

Enum Constant	Description
CANNOT_ACCEPT	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).
CLOSED_ABNORMALLY	1006 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
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.
NO_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.
NO_STATUS_CODE	1005 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
NORMAL_CLOSURE	1000 indicates a normal closure, meaning that the purpose for which the connection was established has been fulfilled.
NOT_CONSISTENT	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 data within a text message).
PROTOCOL_ERROR	1002 indicates that an endpoint is terminating the connection due to a protocol error.
RESERVED	Reserved.
SERVICE_RESTART	1012 indicates that the service will be restarted.
TLS_HANDSHAKE_FAILURE	1015 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
TOO_BIG	1009 indicates that an endpoint is terminating the connection because it has received a message that is too big for it to process.
TRY_AGAIN_LATER	1013 indicates that the service is experiencing overload
UNEXPECTED_CONDITION	1011 indicates that a server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.
VIOLATED_POLICY	1008 indicates that an endpoint is terminating the connection because it has received a message that violates its policy.

Enum Constant Details

NORMAL_CLOSURE

public static final CloseReasons NORMAL_CLOSURE

1000 indicates a normal closure, meaning that the purpose for which the connection was established has been fulfilled.

GOING_AWAY

public static final CloseReasons 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.

PROTOCOL_ERROR

public static final CloseReasons PROTOCOL_ERROR

1002 indicates that an endpoint is terminating the connection due to a protocol error.

CANNOT_ACCEPT

public static final CloseReasons CANNOT_ACCEPT

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).

RESERVED

public static final CloseReasons RESERVED

Reserved. The specific meaning might be defined in the future.

NO_STATUS_CODE

public static final CloseReasons NO_STATUS_CODE

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.

CLOSED_ABNORMALLY

public static final CloseReasons CLOSED_ABNORMALLY

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.

NOT_CONSISTENT

public static final CloseReasons NOT_CONSISTENT

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 data within a text message).

VIOLATED_POLICY

public static final CloseReasons VIOLATED_POLICY

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.

TOO_BIG

public static final CloseReasons TOO_BIG

1009 indicates that an endpoint is terminating the connection because it has received a message that is too big for it to process.

NO_EXTENSION

public static final CloseReasons NO_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 that 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.

UNEXPECTED_CONDITION

public static final CloseReasons 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 CloseReasons SERVICE_RESTART

1012 indicates that the service will be restarted.

TRY_AGAIN_LATER

public static final CloseReasons TRY_AGAIN_LATER

1013 indicates that the service is experiencing overload

TLS_HANDSHAKE_FAILURE

public static final CloseReasons TLS_HANDSHAKE_FAILURE

1015 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 due to a failure to perform a TLS handshake (e.g., the server certificate can't be verified).

Method Details
