Examples of org.apache.hadoop.hbase.filter.FamilyFilter

org.apache.hadoop.hbase.filter.FamilyFilter
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 {@link org.apache.hadoop.hbase.filter.WhileMatchFilter} and {@link org.apache.hadoop.hbase.filter.SkipFilter}to add more control.
Multiple filters can be combined using {@link org.apache.hadoop.hbase.filter.FilterList}.
If an already known column family is looked for, use {@link org.apache.hadoop.hbase.client.Get#addFamily(byte[])}directly rather than a filter.

        filter = new DependentColumnFilter(Base64.decode(family),
            qualifier != null ? Base64.decode(qualifier) : null,
            dropDependentColumn, CompareOp.valueOf(op), comparator.build());
        break;
      case FamilyFilter:
        filter = new FamilyFilter(CompareOp.valueOf(op), comparator.build());
        break;
      case FilterList: {
        List<Filter> list = new ArrayList<Filter>();
        for (FilterModel model: filters) {
          list.add(model.build());
