Enum ParentControllerRegionState

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ParentControllerRegionState>
    public enum ParentControllerRegionState
extends java.lang.Enum<ParentControllerRegionState>
    Enum representing the state of the region where the parent controller resides. i.e., Region dc-0 is ACTIVE while Region dc-1 is PASSIVE This means that ParentController in dc-0 is serving requests while ParentController in dc-1 is rejecting requests

      • ACTIVE

        public static final ParentControllerRegionState ACTIVE
        The region is active, so the parent controller in the region is serving requests

      • PASSIVE

        public static final ParentControllerRegionState PASSIVE
        The region is passive, so the parent controller in the region is rejecting requests. This region is ready to take over if components in the currently active region fails

      • values

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

      • valueOf

        public static ParentControllerRegionState 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
