private static class SimpleRpcScheduler.CallPriorityComparator
extends Object
implements Comparator<CallRunner>
```
Comparator used by the "normal callQueue" if DEADLINE_CALL_QUEUE_CONF_KEY is set to true. It uses the calculated "deadline" e.g. to deprioritize long-running job If multiple requests have the same deadline BoundedPriorityBlockingQueue will order them in FIFO (first-in-first-out) manner.
