Enum ReactorEvent

java.lang.Object
  java.lang.Enum<ReactorEvent>
      org.simpleframework.transport.reactor.ReactorEvent

All Implemented Interfaces:

Serializable, Comparable<ReactorEvent>

public enum ReactorEvent
extends Enum<ReactorEvent>

The ReactorEvent enumeration is used for tracing the operations that occur within the reactor. This is useful when the performance of the system needs to be monitored or when there is a resource or memory consumption issue that needs to be debugged.

Enum Constant Summary

ALREADY_SELECTING
This is used to indicate the channel is already selecting.

CHANNEL_CLOSED
This occurs on an attempt to register an closed channel.

CLOSE_SELECTOR
This occurs when the selector has been shutdown globally.

ERROR
This occurs if there is an error with the selection.

EXECUTE_ACTION
This is the final action of executing the action.

INTEREST_READY
This indicates that the I/O interest has been satisfied.

INVALID_KEY
This occurs rarely however it indicates an invalid registration.

READ_INTEREST_READY
This indicates that the I/O read interest has been satisfied.

REGISTER_INTEREST
This occurs upon the initial registration of an I/O interest.

REGISTER_READ_INTEREST
This occurs upon the initial registration of a read I/O interest.

REGISTER_WRITE_INTEREST
This occurs upon the initial registration of a write I/O interest.

SELECT
This event indicates the registration of an I/O interest.

SELECT_CANCEL
This occurs when a selection key is cancelled for all interests.

SELECT_EXPIRED
This indicates that the selected I/O interest has not occurred.

UPDATE_INTEREST
This is used to indicate the operation interest changed.

UPDATE_READ_INTEREST
This occurs upon the initial registration of a read I/O interest.

UPDATE_WRITE_INTEREST
This occurs upon the initial registration of a write I/O interest.

WRITE_INTEREST_READY
This indicates that the I/O write interest has been satisfied.

Method Detail

values

public static ReactorEvent[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ReactorEvent c : ReactorEvent.values())
    System.out.println(c);

Returns:

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

valueOf

public static ReactorEvent 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
