      • registerForNotifications

        boolean registerForNotifications​(Notifier.Notification targets,
                                         Notifier.NotificationListener callbackObject)
                                  throws java.lang.IllegalArgumentException
        Registers for notifications within the target Containers/Entries

        You can only register for notifications that are at paths within the container this notifier is from. Attempting to use this Notifier with other Containers or Entries (from unrelated containers, nested containers, or nested nested), will result in an IllegalArgumentException.

        Note: listeners should be removed from the same notifier instance they are added to.

        Parameters:
        targets - the locations to monitor for change
        callbackObject - the listener to notify if changes occur to entities in the target collection *
        Returns:
        true if the registration was successful, false otherwise.
        Throws:
        java.lang.IllegalArgumentException - if any Container within targets is a new root, or beneath a new root for this notifier, or a container associated with a different notifier.
