Class OutageSvcTimesList

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<Outage>, java.util.Collection<Outage>, java.util.List<Outage>, java.util.RandomAccess
    public class OutageSvcTimesList
extends java.util.ArrayList<Outage>
     This contains a list of service lost/regained set/pair.

  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 view outage time for
  a window is calculated, the same calculations are not done on the node multiple
  times
