SplitBrainProtectionFunctions which implement this interface will be notified of member heartbeats.

  Modifier and Type Method Description
  
  void onHeartbeat(Member member, long timestamp)
  Notifies of a received heartbeat.

- Method Detail
  - onHeartbeat
```
void onHeartbeat(Member member,
                 long timestamp)
```
    Notifies of a received heartbeat. This method is always invoked before SplitBrainProtectionFunction.apply(Collection) so the SplitBrainProtectionFunction can update its internal state before deciding on whether the minimum cluster size property (for the purpose of split brain detection) is satisfied.
    
    Parameters:
    
    member - member from which heartbeat was received
    
    timestamp - timestmap on which heartbeat was received
