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.

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

put_string

to_string

from_string

to_store

from_store

These methods have custom implementations.
