@InterfaceAudience.Public @InterfaceStability.Stable public class TimestampsFilter
Filter that returns only cells whose timestamp (version) is in the specified list of timestamps (versions).
Note: Use of this filter overrides any time range/time stamp
options specified using Get.setTimeRange(long, long),
Scan.setTimeRange(long, long), Get.setTimeStamp(long),
or Scan.setTimeStamp(long).
