com.elastisys.scale.cloudpool.api.types.ServiceState

All Implemented Interfaces:

Serializable, Comparable<ServiceState>

public enum ServiceState
extends Enum<ServiceState>

The range of permissible service states that a Machine can take on.

The service state, is the operational state of the service running on the machine. This is different from the MachineState, which is the execution state of the Machine as reported by the infrastructure.

Enum Constant Summary

Enum Constants

Enum Constant and Description
BOOTING The service is being bootstrapped and may not (yet) be operational.
IN_SERVICE The service is operational and ready to accept work (health checks pass).
OUT_OF_SERVICE The service is unhealthy and is in need of repair.
UNHEALTHY The service is not functioning properly (health checks fail).
UNKNOWN The service state of the machine cannot be (or has not yet been) determined.

Method Summary

Modifier and Type	Method and Description
static ServiceState	valueOf(String name) Returns the enum constant of this type with the specified name.

Enum Constant Detail

UNKNOWN

public static final ServiceState UNKNOWN

The service state of the machine cannot be (or has not yet been) determined.

BOOTING

public static final ServiceState BOOTING

The service is being bootstrapped and may not (yet) be operational.

IN_SERVICE

public static final ServiceState IN_SERVICE

The service is operational and ready to accept work (health checks pass).

UNHEALTHY

public static final ServiceState UNHEALTHY

The service is not functioning properly (health checks fail).

OUT_OF_SERVICE

public static final ServiceState OUT_OF_SERVICE

The service is unhealthy and is in need of repair. It should be considered out of service and not able to accept work until it has recovered. Machines in this service state are not to be considered part of the active machine pool and candidates for being replaced.

Method Detail

values

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

Returns:

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

valueOf

public static ServiceState 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
