      • getPriority

        public int getPriority​(Event event)
        Description copied from interface: Observer
        Retrieves the priority to observe this event.
        This can be used to process a supported event before others observers.
        Specified by:
        getPriority in interface Observer
        Parameters:
        event - the event.
        Returns:
