Examples of org.apache.hadoop.hbase.io.TimeRange

org.apache.hadoop.hbase.io.TimeRange
Represents an interval of version timestamps.
Evaluated according to minStamp <= timestamp < maxStamp or [minStamp,maxStamp) in interval notation.
Only used internally; should not be accessed directly by clients.

    client.shutdown();
