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

org.apache.hadoop.hbase.filter.WhileMatchRowFilter
WhileMatchRowFilter is a wrapper filter that filters everything after the first filtered row. Once the nested filter returns true for either of it's filter(..) methods or filterNotNull(SortedMap), this wrapper's filterAllRemaining() will return true. All filtering methods will thereafter defer to the result of filterAllRemaining().

      newFilter = new WhileMatchFilter(new InclusiveStopFilter(stopRow));
      scan = new Scan();
      scan.setFilter(newFilter);
      rowInclusiveStopFilter(scan, stopRow);
      
      oldFilter = new WhileMatchRowFilter(
          new InclusiveStopRowFilter(stopRow));
      scan = new Scan();
      scan.setOldFilter(oldFilter);
      rowInclusiveStopFilter(scan, stopRow);
