Solve the following python programming problem given the following code:
def queryAll(self, * args, **kwargs) : 
    '
        Returns a :class:`Deferred` object which will have its callback invoked
        with a :class:`BatchedView` when the results are complete.

        Parameters follow conventions of
        :meth:`~couchbase.bucket.Bucket.query`.

        Example::

          d = cb.queryAll("beer", "brewery_beers")
          def on_all_rows(rows):
              for row in rows:
                 print("Got row {0}".format(row))

          d.addCallback(on_all_rows)

        ' 
    if (not cb.connected) : 
        cb = (lambda x : self.queryAll (* args, ** kwargs)) 
        return self.connect ().addCallback (cb) 
kwargs ['itercls'] = BatchedView 
    o = super (RawBucket, self).query (* args, ** kwargs) 
    o.start () 
    return o._getDeferred () 

    
    

    Fix the buggy line: if (not cb.connected) :

#Here is Python code to fix the buggy line: if (not cb.
