        public static final WatchMode successOnly
        The CompletionStage<org.apache.zookeeper.WatchedEvent> will only complete on successful trigger. i.e. connection issues are ignored

      • stateChangeOnly

        public static final WatchMode stateChangeOnly
        The CompletionStage<org.apache.zookeeper.WatchedEvent> will only completeExceptionally. Successful trigger is ignored. Connection exceptions are of type: AsyncEventException.

      • stateChangeAndSuccess

        public static final WatchMode stateChangeAndSuccess

    • Method Detail

      • values

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

      • valueOf

        public static WatchMode 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
