  • All Implemented Interfaces:
    Serializable, Comparable<ApplicationState>

    public enum ApplicationState
    extends Enum<ApplicationState>
    The current state of the server.

    Possible state transitions are:

    • STARTING -> (FIRST_RUN | RUNNING | ERROR | STOPPING)
    • FIRST_RUN -> (RUNNING | ERROR | STOPPING)
    • RUNNING -> (ERROR | STOPPING)
    • ERROR -> (RUNNING | STOPPING)
    • STOPPING ->
    • Enum Constant Detail

      • STARTING

        public static final ApplicationState STARTING
        The application is starting up, but not yet available
      • FIRST_RUN

        public static final ApplicationState FIRST_RUN
        The application is running for the first time and has not yet been configured.
      • RUNNING

        public static final ApplicationState RUNNING
        The application has been setup and is running normally
      • ERROR

        public static final ApplicationState ERROR
        The application is currently not available because of an error
      • STOPPING

        The application is shutting down
    • Method Detail

      • values

        public static ApplicationState[] 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 (ApplicationState c : ApplicationState.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static ApplicationState 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
