Enum AddWatchMode

    • Enum Constant Detail

      • PERSISTENT

        public static final AddWatchMode PERSISTENT

        Set a watcher on the given path that does not get removed when triggered (i.e. it stays active until it is removed). This watcher is triggered for both data and child events. To remove the watcher, use removeWatches() with WatcherType.Any. The watcher behaves as if you placed an exists() watch and a getData() watch on the ZNode at the given path.

      • PERSISTENT_RECURSIVE

        public static final AddWatchMode PERSISTENT_RECURSIVE

        Set a watcher on the given path that: a) does not get removed when triggered (i.e. it stays active until it is removed); b) applies not only to the registered path but all child paths recursively. This watcher is triggered for both data and child events. To remove the watcher, use removeWatches() with WatcherType.Any

        The watcher behaves as if you placed an exists() watch and a getData() watch on the ZNode at the given path and any ZNodes that are children of the given path including children added later.

        NOTE: when there are active recursive watches there is a small performance decrease as all segments of ZNode paths must be checked for watch triggering.

    • Method Detail

      • values

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

      • valueOf

        public static AddWatchMode 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
