throws PortalException
This method checks for the view permission when retrieving the container models.
Useful when paginating results. Returns a maximum of end -
start instances. The start and 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 and end to QueryUtil.ALL_POS will return the full
result set.

PortalExceptionString getDeleteMessage()
If the language key (e.g. found-in-deleted-folder-x) used
accepts a single parameter, the trash framework replaces that parameter
with the trashed container's name.
