Service.State (Guava: Google Core Libraries for Java 19.0 API)

java.lang.Object
- java.lang.Enum<Service.State>
- - com.google.common.util.concurrent.Service.State

All Implemented Interfaces:

Serializable, Comparable<Service.State>

Enclosing interface:

Service
```
@Beta
public static enum Service.State
extends Enum<Service.State>
```
The lifecycle states of a service.
The ordering of the Service.State enum is defined such that if there is a state transition from A -> B then A.compareTo(B < 0}. N.B. The converse is not true, i.e. if A.compareTo(B < 0} then there is not guaranteed to be a valid state transition A -> B.

Since:

9.0 (in 1.0 as com.google.common.base.Service.State)

```
    A service in this state is transitioning to RUNNING.
  - RUNNING
```
public static final Service.State RUNNING
```
    A service in this state is operational.
  - STOPPING
```
public static final Service.State STOPPING
```
    A service in this state is transitioning to TERMINATED.
  - TERMINATED
```
public static final Service.State TERMINATED
```
    A service in this state has completed execution normally. It does minimal work and consumes minimal resources.
  - FAILED
```
public static final Service.State FAILED
```
    A service in this state has encountered a problem and may not be operational. It cannot be started nor stopped.
- Method Detail
  - values
```
public static Service.State[] 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 (Service.State c : Service.State.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Service.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
