NAME
Data::BitStream::WordVec - A Vector-32 implementation of Data::BitStream
SYNOPSIS
use Data::BitStream::WordVec;
my $stream = Data::BitStream::WordVec->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 32-bit units, which makes it safe for 32-bit and 64-bit machines as well as reasonably time efficient.
This is the default Data::BitStream implementation.
