public interface HInternalScannerInterface
Internally, we need to be able to determine if the scanner is doing wildcard column matches (when only a column family is specified or if a column regex is specified) or if multiple members of the same column family were specified. If so, we need to ignore the timestamp to ensure that we get all the family members, as they may have been last updated at different times.
