This method checks for the view permission when retrieving the container models.
Useful when paginating results. Returns a maximum of end -

values are not primary keys but, rather, indexes in the result set. Thus,
0
refers to the first result in the set. Setting both
start

to QueryUtil.ALL_POS
will return the full
