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

org.apache.hadoop.hbase.filter.RowFilterSet
Implementation of RowFilterInterface that represents a set of RowFilters which will be evaluated with a specified boolean operator MUST_PASS_ALL (!AND) or MUST_PASS_ONE (!OR). Since you can use RowFilterSets as children of RowFilterSet, you can create a hierarchy of filters to be evaluated.

        StopRowFilter stopFilter = (StopRowFilter) wmrFilter
            .getInternalFilter();
        return stopFilter.getStopRowKey();
      }
    } else if (filter instanceof RowFilterSet) {
      RowFilterSet rowFilterSet = (RowFilterSet) filter;
      if (rowFilterSet.getOperator()
          .equals(RowFilterSet.Operator.MUST_PASS_ALL)) {
        for (RowFilterInterface subFilter : rowFilterSet.getFilters()) {
          byte[] endRow = getEndRow(subFilter);
          if (endRow != null) {
            return endRow;
          }
        }
