NAME ^

Data::BitStream::MinimalVec - A minimal implementation of Data::BitStream

SYNOPSIS ^

  use Data::BitStream::MinimalVec;
  my $stream = Data::BitStream::MinimalVec->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, and shows basically the minimal work required to get an implementation working. Everything else is provided by the base class. It is slow, and Data::BitStream::WordVec is recommended for real work.

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

These methods have custom implementations.
