All Implemented Interfaces:: Runnable

class ACKTimerextends SimpleTimer2.TimedEvent

Timer for sending ratchet-layer acknowledgments when application responses are delayed, supporting NS, NSR, ACK requests, and forward next key blocks.

The vast majority of these will be cancelled before firing, when streaming sends a response. This should only fire if streaming drops completely, and for certain datagram traffic patterns.
