java.lang.Object
public class TimeWindowedList
Keeps a list of timestamped values that are in the given time-period (millis). It also guarantees to keep the given minimum number of values in the list (even if old), and to keep the given number of out-of-date values. For example, this is useful if we want to determine if a metric has been consistently high.
