Method Detail

getTimeOfNodeBeingInCurrentState

public java.time.Duration getTimeOfNodeBeingInCurrentState(Node node,
                                                           java.time.Clock clock)

Parameters:

node -

Returns:

how long node is in current state if duration will be negative it will return duration equal to 0

getEstimatedRetentionTime

public java.time.Duration getEstimatedRetentionTime(Node node,
                                                    java.time.Duration retentionPeriod,

Parameters:

node -

Returns:

how much time left to consider this node as retained if duration will be negative it will return duration equal to 0

isNodeHeartbeatValid

public boolean isNodeHeartbeatValid(Node node)

Check if nodes heartbeat is valid

Returns:

true if nodes heartbeat is not null, greater than zero and greater than timestamp, otherwise false
