This is a legacy method, implementing old-style (Joomla! 3.x) plugin calls. It's best to go directly through the Dispatcher and handle the returned EventInterface object instead of going through this method. This method is deprecated and will be removed in Joomla! 5.x.

This method will only return the 'result' argument of the event
