@InterfaceAudience.Public @InterfaceStability.Stable public class ValueFilter extends CompareFilter
This filter can be wrapped with WhileMatchFilter
and SkipFilter
to add more control.
Multiple filters can be combined using FilterList
.
To test the value of a single qualifier when scanning multiple qualifiers,
use SingleColumnValueFilter
.
