Field Summary

static int	ABNORMAL_CLOSE a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
static int	END_POINT_GOING_DOWN Indicates that an endpoint is "going away", such as a server going down, or a browser having navigated away from a page.
static int	INVALID_DATA Indicates that an endpoint is terminating the connection because it has received a type of data it cannot accept (e.g.
static int	MESSAGE_TOO_LARGE indicates that an endpoint is terminating the connection because it has received a message that is too large.
static int	NO_STATUS_CODE a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
static int	NORMAL_CLOSURE Indicates a normal closure, meaning whatever purpose the connection was established for has been fulfilled.
static int	PROTOCOL_ERROR Indicates that an endpoint is terminating the connection due to a protocol error.

Field Detail

NORMAL_CLOSURE

static final int NORMAL_CLOSURE

Indicates a normal closure, meaning whatever purpose the connection was established for has been fulfilled.

END_POINT_GOING_DOWN

static final int END_POINT_GOING_DOWN

Indicates that an endpoint is "going away", such as a server going down, or a browser having navigated away from a page.

Constant Field Values

PROTOCOL_ERROR

static final int PROTOCOL_ERROR

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

Constant Field Values

INVALID_DATA

static final int INVALID_DATA

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

MESSAGE_TOO_LARGE

static final int MESSAGE_TOO_LARGE

indicates that an endpoint is terminating the connection because it has received a message that is too large.

Constant Field Values

NO_STATUS_CODE

static final int NO_STATUS_CODE

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

static final int ABNORMAL_CLOSE

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.
