java.lang.Enum<SocketEvent>

org.apache.tomcat.util.net.SocketEvent

All Implemented Interfaces:

Serializable, Comparable<SocketEvent>, java.lang.constant.Constable

public enum SocketEvent
extends Enum<SocketEvent>

Defines events that occur per socket that require further processing by the container. Usually these events are triggered by the socket implementation but they may be triggered by the container.

Enum Constant Summary

Enum Constants

Enum Constant	Description
CONNECT_FAIL	A client attempted to establish a connection but failed.
DISCONNECT	The client has disconnected.
ERROR	An error has occurred on a non-container thread and processing needs to return to the container for any necessary clean-up.
OPEN_READ	Data is available to be read.
OPEN_WRITE	The socket is ready to be written to.
STOP	The associated Connector/Endpoint is stopping and the connection/socket needs to be closed cleanly.
TIMEOUT	A timeout has occurred and the connection needs to be closed cleanly.

Method Summary

Modifier and Type	Method	Description
static SocketEvent	valueOf(String name)	Returns the enum constant of this type with the specified name.
static SocketEvent[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Details

OPEN_READ

public static final SocketEvent OPEN_READ

Data is available to be read.

OPEN_WRITE

public static final SocketEvent OPEN_WRITE

The socket is ready to be written to.

STOP

public static final SocketEvent STOP

The associated Connector/Endpoint is stopping and the connection/socket needs to be closed cleanly.

TIMEOUT

public static final SocketEvent TIMEOUT

A timeout has occurred and the connection needs to be closed cleanly. Currently this is only used by the Servlet 3.0 async processing.

DISCONNECT

public static final SocketEvent DISCONNECT

The client has disconnected.

ERROR

public static final SocketEvent ERROR

An error has occurred on a non-container thread and processing needs to return to the container for any necessary clean-up. Examples of where this is used include:

• by NIO2 to signal the failure of a completion handler
• by the container to signal an I/O error on a non-container thread during Servlet 3.0 asynchronous processing.

CONNECT_FAIL

public static final SocketEvent CONNECT_FAIL

A client attempted to establish a connection but failed. Examples of where this is used include:

• TLS handshake failures

Method Details

values

public static SocketEvent[] values()

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

Returns:

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

valueOf

public static SocketEvent valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null
