# Enum AbstractCircuitBreaker.State

java.lang.Object
java.lang.Enum<AbstractCircuitBreaker.State>
org.apache.commons.lang3.concurrent.AbstractCircuitBreaker.State

All Implemented Interfaces:
  `Serializable, Comparable<AbstractCircuitBreaker.State>`

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`.

Since:
  3.5

  - ### 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 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 AbstractCircuitBreaker.State 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

  - ### 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
