   *   a dot and the actual event name (e.g. "mymodule.my_event").
   * @param int $window
   *   (optional) Number of seconds before this event expires. Defaults to 3600
   *   (1 hour). Typically uses the same value as the isAllowed() $window
   *   parameter. Expired events are purged on cron run to prevent the flood
   *   table from growing indefinitely.

   *   (optional) Unique identifier of the current user. Defaults to the current
   *   user's IP address).
