gannuWSD.skipfilters.SkipFilter

Template Class for creating a new SkipFilter. An SkipFilter object tells if a word should be disambiguated or not. These methods are useful for avoiding words that you know that they cannot be disambiguated before hand. @author Francisco Viveros-Jiménez

org.apache.hadoop.hbase.filter.SkipFilter

A wrapper filter that filters an entire row if any of the KeyValue checks do not pass.

For example, if all columns in a row represent weights of different things, with the values being the actual weights, and we want to filter out the entire row if any of its weights are zero. In this case, we want to prevent rows from being emitted if a single key is filtered. Combine this filter with a {@link ValueFilter}:

 scan.setFilter(new SkipFilter(new ValueFilter(CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(0))));  Any row which contained a column whose value was 0 will be filtered out. Without this filter, the other non-zero valued columns in the row would still be emitted.

        // vv SkipFilterExample
      }
    }
    scanner1.close();


    Filter filter2 = new SkipFilter(filter1);


    scan.setFilter(filter2); // co SkipFilterExample-2-AddFilter2 Add the decorating skip filter for the second scan.
    ResultScanner scanner2 = table.getScanner(scan);
    // ^^ SkipFilterExample
    System.out.println("Total KeyValue count for scan #1: " + n);
