/**
* Mechanism for monitoring and controlling delivery of files to a destination.
- *
- * <p>The DeliveryQueue class maintains lists of DeliveryTasks for a single destination (a subscription or another data
- * router node) and assigns delivery threads to try to deliver them. It also maintains a delivery status that causes it
- * to back off on delivery attempts after a failure.
- *
- * <p>If the most recent delivery result was a failure, then no more attempts will be made for a period of time.
- * Initially, and on the first failure following a success, this delay will be DeliveryQueueHelper.getInitFailureTimer()
- * (milliseconds). If, after this delay, additional failures occur, each failure will multiply the delay by
- * DeliveryQueueHelper.getFailureBackoff() up to a maximum delay specified by DeliveryQueueHelper.getMaxFailureTimer().
- * Note that this behavior applies to the delivery queue as a whole and not to individual files in the queue. If
- * multiple files are being delivered and one fails, the delay will be started. If a second delivery fails while the
- * delay was active, it will not change the delay or change the duration of any subsequent delay. If, however, it
- * succeeds, it will cancel the delay.
- *
- * <p>The queue maintains 3 collections of files to deliver: A to do list of files that will be attempted, a working
- * set of files that are being attempted, and a retry set of files that were attempted and failed. Whenever the to do
- * list is empty and needs to be refilled, a scan of the spool directory is made and the file names sorted. Any files
- * in the working set are ignored. If a DeliveryTask for the file is in the retry set, then that delivery task is placed
- * on the to do list. Otherwise, a new DeliveryTask for the file is created and placed on the to do list. If, when a
- * DeliveryTask is about to be removed from the to do list, its age exceeds DeliveryQueueHelper.getExpirationTimer(),
- * then it is instead marked as expired.
- *
- * <p>A delivery queue also maintains a skip flag. This flag is true if the failure timer is active or if no files are
- * found in a directory scan.
