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.
