Enum Service.State

  • All Implemented Interfaces:
    Serializable, Comparable<Service.State>
    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.

    • Enum Constant Detail

      • NEW

        public static final Service.State NEW
        A service in this state is inactive. It does minimal work and consumes minimal resources.
      • 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
