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.
