# Plucene::Bitvector(3pm)

a vector of bits

## NAME

Plucene::Bitvector - a vector of bits

## SYNOPSIS

```
        # isa Bit::Vector::Minimal;
        my $bitvector = Plucene::Bitvector->read($stream);
        $bitvector->write($stream);

        my $count = $bitvector->count;
```

## DESCRIPTION

A serialisable implementation of a vector of bits.

This subclass of Bit::Vector::Minimal allows the writing (and reading) of  vectors to (and from) 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 $bitvector = Plucene::Bitvector->read($stream);
```

Read from the passed in stream.
