Enum Class AbstractCircuitBreaker.State

java.lang.Object

java.lang.Enum<AbstractCircuitBreaker.State>

edu.internet2.middleware.grouperClientExt.org.apache.commons.lang3.concurrent.AbstractCircuitBreaker.State

All Implemented Interfaces:

Serializable, Comparable<AbstractCircuitBreaker.State>, java.lang.constant.Constable

Enclosing class:

AbstractCircuitBreaker<T>

protected static enum AbstractCircuitBreaker.State
extends Enum<AbstractCircuitBreaker.State>

An internal enumeration representing the different states of a circuit breaker. This class also contains some logic for performing state transitions. This is done to avoid complex if-conditions in the code of CircuitBreaker.

Enum Constant Details

CLOSED

public static final AbstractCircuitBreaker.State CLOSED

The closed state.

OPEN

public static final AbstractCircuitBreaker.State OPEN

The open state.

Method Details

values

public static AbstractCircuitBreaker.State[] 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 AbstractCircuitBreaker.State 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

oppositeState

public abstract AbstractCircuitBreaker.State oppositeState()

Returns the opposite state to the represented state. This is useful for flipping the current state.

Returns:

the opposite state
