docs: Call the appenders in the hierrachy starting at <code>this</code>. If no appenders could be found, emit a warning.
  
  <p>
  This method calls all the appenders inherited from the hierarchy circumventing any evaluation of whether to log or not to log the
  particular log request.
  
  @param event the event to log.
