    a Plucene stream.

## METHODS
  count
            my $count = $bitvector->count;

    Compute the number of one-bits.

  write
            $bitvector->write($stream);

    Write this vector to the passed in stream.

  read
            my $bitvector = [Plucene::Bitvector](https://www.chedong.com/phpMan.php/perldoc/Plucene%3A%3ABitvector/markdown)->read($stream);
