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

org.apache.hadoop.hbase.filter.BinaryComparator
A binary comparator which lexicographically compares against the specified byte array using {@link Bytes#compareTo(byte[],byte[])}.

    // Make sure key is of some substance... non-null and > than first key.
    assertTrue(key != null && key.length > 0 &&
      Bytes.BYTES_COMPARATOR.compare(key, new byte [] {'a', 'a', 'a'}) >= 0);
    LOG.info("Key=" + Bytes.toString(key));
    Scan s = startRow == null? new Scan(): new Scan(startRow);
    Filter f = new RowFilter(op, new BinaryComparator(key));
    f = new WhileMatchFilter(f);
    s.setFilter(f);
    return s;
