Enum Constant Summary

Enum Constants

Enum Constant	Description
CANCEL	Used by the endpoint to indicate that the stream is no longer needed.
COMPRESSION	The endpoint is unable to maintain the header compression context for the connection.
CONNECT	The connection established in response to a CONNECT request (Section 8.3) was reset or abnormally closed.
ENHANCE_YOUR_CALM	The endpoint detected that its peer is exhibiting a behavior that might be generating excessive load.
FLOW_CONTROL	The endpoint detected that its peer violated the flow-control protocol.
FRAME_SIZE	The endpoint received a frame with an invalid size.
HTTP_1_1_REQUIRED	The endpoint requires that HTTP/1.1 be used instead of HTTP/2.
INADEQUATE_SECURITY	The underlying transport has properties that do not meet minimum security requirements (see Section 9.2).
INTERNAL	The endpoint encountered an unexpected internal error.
NO_ERROR	The associated condition is not a result of an error.
PROTOCOL	The endpoint detected an unspecific protocol error.
REFUSED_STREAM	The endpoint refused the stream prior to performing any application processing (see Section 8.1.4 for details).
REQUEST_HEADER_FIELDS_TOO_LARGE	Request header fields are too large.
SETTINGS_TIMEOUT	The endpoint sent a SETTINGS frame but did not receive a response in a timely manner.
STREAM_CLOSED	The endpoint received a frame after a stream was half-closed.

Method Summary

Modifier and Type	Method	Description

Enum Constant Details

NO_ERROR

public static final Http2ErrorCode NO_ERROR

The associated condition is not a result of an error. For example, a GOAWAY might include this code to indicate graceful shutdown of a connection.

PROTOCOL

public static final Http2ErrorCode PROTOCOL

The endpoint detected an unspecific protocol error. This error is for use when a more specific error code is not available.

INTERNAL

public static final Http2ErrorCode INTERNAL

The endpoint encountered an unexpected internal error.

FLOW_CONTROL

public static final Http2ErrorCode FLOW_CONTROL

The endpoint detected that its peer violated the flow-control protocol.

SETTINGS_TIMEOUT

public static final Http2ErrorCode SETTINGS_TIMEOUT

The endpoint sent a SETTINGS frame but did not receive a response in a timely manner. See Section 6.5.3 ("Settings Synchronization").

STREAM_CLOSED

public static final Http2ErrorCode STREAM_CLOSED

The endpoint received a frame after a stream was half-closed.

FRAME_SIZE

public static final Http2ErrorCode FRAME_SIZE

The endpoint received a frame with an invalid size.

REFUSED_STREAM

public static final Http2ErrorCode REFUSED_STREAM

The endpoint refused the stream prior to performing any application processing (see Section 8.1.4 for details).

CANCEL

public static final Http2ErrorCode CANCEL

Used by the endpoint to indicate that the stream is no longer needed.

COMPRESSION

public static final Http2ErrorCode COMPRESSION

The endpoint is unable to maintain the header compression context for the connection.

CONNECT

public static final Http2ErrorCode CONNECT

The connection established in response to a CONNECT request (Section 8.3) was reset or abnormally closed.

ENHANCE_YOUR_CALM

public static final Http2ErrorCode ENHANCE_YOUR_CALM

The endpoint detected that its peer is exhibiting a behavior that might be generating excessive load.

INADEQUATE_SECURITY

public static final Http2ErrorCode INADEQUATE_SECURITY

The underlying transport has properties that do not meet minimum security requirements (see Section 9.2).

HTTP_1_1_REQUIRED

public static final Http2ErrorCode HTTP_1_1_REQUIRED

The endpoint requires that HTTP/1.1 be used instead of HTTP/2.

REQUEST_HEADER_FIELDS_TOO_LARGE

public static final Http2ErrorCode REQUEST_HEADER_FIELDS_TOO_LARGE

Request header fields are too large. RFC6585

Method Details

values

public static Http2ErrorCode[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Http2ErrorCode valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

get

public static Http2ErrorCode get(int errorCode)

Get error code enum based on error code number.

Parameters:

errorCode - error code

Returns:

enum for the error code, returns INTERNAL when not found

code

public int code()

Numeric code of this error.

Returns:

error code
