EntryFilteringCursor	list(NextInterceptor nextInterceptor, ListOperationContext opContext) Checks to see the base being searched exists, otherwise throws the appropriate LdapException.
ClonedServerEntry	lookup(NextInterceptor nextInterceptor, LookupOperationContext opContext) Checks to see the base being searched exists, otherwise throws the appropriate LdapException.
void	modify(NextInterceptor nextInterceptor, ModifyOperationContext opContext) Checks to see the entry being modified exists, otherwise throws the appropriate LdapException.
void	move(NextInterceptor nextInterceptor, MoveOperationContext opContext) Checks to see the entry being moved exists, and so does its parent, otherwise throws the appropriate LdapException.
