NAME

       Rose::DB::Object::Iterator - Iterate over a series of Rose::DB::Objects.

SYNOPSIS

           $iterator = Rose::DB::Object::Manager->get_objects_iterator(...);

           while($object = $iterator->next)
           {
             # do stuff with $object...

             if(...) # bail out early
             {
               $iterator->finish;
               last;
             }
           }

           if($iterator->error)
           {
             print "There was an error: ", $iterator->error;
           }
           else
           {
             print "Total: ", $iterator->total;
           }

DESCRIPTION

       Rose::DB::Object::Iterator is an iterator object that traverses a database query, returning
       Rose::DB::Object-derived objects for each row.  Rose::DB::Object::Iterator objects are created by calls
       to the get_objects_iterator method of Rose::DB::Object::Manager or one of its subclasses.

OBJECT METHODS

       error
           Returns the text message associated with the last error, or false if there was no error.

       finish
           Prematurely stop the iteration (i.e., before iterating over all of the available objects).

       next
           Return the next Rose::DB::Object-derived object.  Returns false (but defined) if there are no more
           objects to iterate over, or undef if there was an error.

       total
           Returns the total number of objects iterated over so far.
