Take a look at the following method in HRegionServer:

  public boolean checkAndPut(final byte[] regionName, final byte[] row,
      final byte[] family, final byte[] qualifier, final byte[] value,
      final Put put) throws IOException {

You can create checkAndIncrement() in a similar way.

Cheers
