Class RTCNodeSvcTimesList

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<RTCNodeSvcTime>, java.util.Collection<RTCNodeSvcTime>, java.util.Deque<RTCNodeSvcTime>, java.util.List<RTCNodeSvcTime>, java.util.Queue<RTCNodeSvcTime>
    public class RTCNodeSvcTimesList
extends java.util.LinkedList<RTCNodeSvcTime>
    List of service times. This contains a list of service lost/regained set/pair for the RTCNode. Also maintains the outage/down time each time it is calculated and the time from which this was calculated - this is done so when the outage time for a window is calculated, the same calculations are not done on the node multiple times. 'Expired' outages are removed during 'add' and 'getDownTime' operations.
