@InterfaceAudience.Public @InterfaceStability.Stable public class FamilyFilter extends CompareFilter
This filter is used to filter based on the column family. It takes an operator (equal, greater, not equal, etc) and a byte [] comparator for the column family portion of a key.
This filter can be wrapped with WhileMatchFilter and SkipFilter
to add more control.
Multiple filters can be combined using FilterList.
