| long | getValidWindow()Returns the time range before and after the current reservation considered
 by this policy. | 
| void | init(String reservationQueuePath,

| void | validate(Plan plan,
        ReservationAllocation reservation)The validation algorithm walks over the RLE encoded allocation and
 checks that for all transition points (when the start or end of the
 checking window encounters a value in the RLE). |
