NAME ^

Bit::Vector::Minimal - Object-oriented wrapper around vec()

SYNOPSIS ^

  use Bit::Vector::Minimal;
  my $vec = Bit::Vector->new(size => 8, width => 1, endianness => "little");
  # These are the defaults

  $vec->set(1); # $vec's internal vector now looks like "00000010"
  $vec->get(3); # 0

DESCRIPTION ^

This is a much simplified, lightweight version of Bit::Vector, and wraps Perl's (sometimes confusing) vec function in an object-oriented abstraction.

METHODS ^

new

Creates a new bit vector. By default, this creates a one-byte vector with 8 one-bit "slots", with bit zero on the right of the bit pattern. These settings can be changed by passing parameters to the constructor: size will alter the size in bits of the vector; width will alter the width of the slots. The module will die if width is not an integer divisor of size. endianness controls whether the zeroth place is on the right or the left of the bit vector.

set(POS[, VALUE])

Sets the bit or slot at position POS to value VALUE or "all bits on" if VALUE is not given.

get(POS)

Returns the bit or slot at position POS.

display

Display the vector. For debugging purposes.
