NAME ^

Data::BitStream::Vec - A Vector-1 implementation of Data::BitStream

SYNOPSIS ^

  use Data::BitStream::Vec;
  my $stream = Data::BitStream::Vec->new;
  $stream->put_gamma($_) for (1 .. 20);
  $stream->rewind_for_read;
  my @values = $stream->get_gamma(-1);

DESCRIPTION ^

An implementation of Data::BitStream. See the documentation for that module for many more examples, and Data::BitStream::Base for the API. This document only describes the unique features of this implementation, which is of limited value to people purely using Data::BitStream.

This implementation uses a Perl vec to store the data. The vector is accessed in 1-bit units, which makes it easy and portable, however it is slow. It really is deprecated in favor of Data::BitStream::WordVec.

DATA

_vec

A private scalar holding the data as a vector.

CLASS METHODS

_vecref

Retrieves a reference to the private vector.

after erase

Sets the private vector to the empty string ''.

read
write
put_unary
get_unary
to_string
from_string
to_store
from_store

These methods have custom implementations.
