Enum Constant Detail

CLOSED

public static final CircuitState CLOSED

Initial state. All requests are sent to the remote service.

OPEN

public static final CircuitState OPEN

The circuit is tripped. All requests fail immediately without calling the remote service.

HALF_OPEN

public static final CircuitState HALF_OPEN

Only one trial request is sent at a time until at least one request succeeds or fails. If it doesn't complete within a certain time, another trial request will be sent again. All other requests fails immediately same as OPEN.

Method Detail

values

public static CircuitState[] 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 (CircuitState c : CircuitState.values())
    System.out.println(c);

Returns:

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

valueOf

public static CircuitState 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
