$object
   , string $class_name
   , array $properties_list

       The optional parameter exclude is used to
       decide whether the list contains the names of class properties to
       include in the aggregation (i.e. exclude is
       FALSE), or to exclude from the
       aggregation (exclude is TRUE).
