        targetResultCount - the desired number of results or default to the collection size
        cutOffAfterTimeMs - the number of milliseconds to wait before cut-off or zero to use the system default time-based cut-off.
        cutOffAfterCount - the number of permission checks to process before cut-off or zero to use the system default count-based cut-off.
        Returns:
        a Collection of the same type but including the PermissionCheckCollection interface
