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

        public static Priority valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • downgrade

        public Priority downgrade​(Priority floor)
        Returns the priority one level below the current priority if priority is higher than the specified floor or the lowest available priority. Otherwise return itself.
        Parameters:
        floor - Priority floor
        Returns:
        Priority after downgrade.
      • downgrade

        public Priority downgrade()
        Returns the priority one level below the current priority if priority is higher than the default floor or the lowest available priority. Otherwise return itself.
        Returns:
        Priority after downgrade.
