class DeadlineFailureDetector extends FailureDetector
Implementation of failure detector using an absolute timeout of missing heartbeats to trigger unavailability.
#isAvailable will return false if there is no #heartbeat within the duration
heartbeatInterval + acceptableHeartbeatPause.

Instance Constructors
- new DeadlineFailureDetector(config: Config, ev: EventStream)
Constructor that reads parameters from config.
Constructor that reads parameters from config. Expecting config properties named
acceptable-heartbeat-pause. - new DeadlineFailureDetector(acceptableHeartbeatPause: FiniteDuration, heartbeatInterval: FiniteDuration)(implicit clock: Clock)
- acceptableHeartbeatPause
Duration corresponding to number of potentially lost/delayed heartbeats that will be accepted before considering it to be an anomaly.
- heartbeatInterval
Expected heartbeat interval
- clock
The clock, returning current time in milliseconds, but can be faked for testing purposes. It is only used for measuring intervals (duration).
