Abstract Value Members
- abstract def heartbeat(): Unit
Notifies the FailureDetector that a heartbeat arrived from the monitored resource.
Notifies the FailureDetector that a heartbeat arrived from the monitored resource. This causes the FailureDetector to update its state.
- abstract def isAvailable: Boolean
Returns true if the resource is considered to be up and healthy and returns false otherwise.
- abstract def isMonitoring: Boolean
Returns true if the failure detector has received any heartbeats and started monitoring of the resource.
