Enum Service.State

java.lang.Object
java.lang.Enum<Service.State>
com.google.common.util.concurrent.Service.State
All Implemented Interfaces:
Serializable, Comparable<Service.State>, Constable
Enclosing interface:
Service
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.
