$event->attach('afterSave', '\\Apps\\Components\\applyUserDefinedFunction'); 
or
$event->attach('afterValidation', '\\Apps\\Components\\General@userDefinedFunction');  
or
$event->attach('event', function () {
  echo "Hellow Here.";
}); 

###Trigger An Event

 $event->trigger('event');
or
$event->trigger('beforeSave');

class General 
{
    public function userDefinedFunction()
    {
       echo "Handle your requests. Triggered by Events"; 
    } 
}
