NAME

Data::BitStream::String - A String implementation of Data::BitStream

SYNOPSIS

  use Data::BitStream::String;
  my $stream = Data::BitStream::String->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 is very memory inefficient, as it uses a binary string to hold the data, hence uses one byte internally per bit of data. However it is a useful reference implementation, and since most operations use Perl operations it is quite fast.

DATA

_str

A private string holding the data in binary string form.

CLASS METHODS

_strref

Retrieves a reference to the private string.

after erase

Sets the private string to the empty string ''.

put_unary
get_unary

These methods have custom implementations.
