Interface PhysicalSlotRequestBulkChecker

All Known Implementing Classes:
PhysicalSlotRequestBulkCheckerImpl
public interface PhysicalSlotRequestBulkChecker
This class tracks a fulfillability timeout of a bulk of physical slot requests.

The check stops when all pending physical slot requests of PhysicalSlotRequestBulk are fulfilled by available or newly allocated slots. The bulk is fulfillable if all its physical slot requests can be fulfilled either by available or newly allocated slots or slots which currently used by other job subtasks. The bulk gets canceled if the timeout occurs and the bulk is not fulfillable. The timeout timer is not running while the bulk is fulfillable but not fulfilled yet.
