NAME

List::Rubyish::Circular - A circular list implementation based on List::Rubyish

SYNOPSIS

  use Test::More;
  use List::Rubyish::Circular;

  my $list = List::Rubyish::Circular->new(qw(jkondo reikon cinnamon));

  is_deeply [qw(reikon cinnamon jkondo)], $list->cycle->to_a;
  is_deeply [qw(cinnamon jkondo reikon)], $list->cycle(2)->to_a;

  is_deeply [qw(cinnamon jkondo reikon)], $list->rcycle->to_a;
  is_deeply [qw(reikon cinnamon jkondo)], $list->rcycle(2)->to_a;

  # $list is still a circular list after destracive operation
  $list->push(qw(tokky));

  is_deeply [qw(jkondo reikon cinnamon tokky)], $list->to_a;
  is_deeply [qw(reikon cinnamon tokky jkondo)], $list->cycle->to_a;
  is_deeply [qw(cinnamon tokky jkondo reikon)], $list->rcycle(2)->to_a;

DESCRIPTION

List::Rubyish::Circular is a cirlular list implementation besed on List::Rubyish, so that You can utilize some convenient methods from List::Rubyish against a circular list.

METHODS

cycle ( $count )

Shifts list to the left according to $count and returns new list $count. If $count not passed in, its value is 1.

  my $list = List::Rubyish::Circular->new(qw(jkondo reikon cinnamon));

  is_deeply [qw(reikon cinnamon jkondo)], $list->cycle->to_a;
  is_deeply [qw(cinnamon jkondo reikon)], $list->cycle(2)->to_a;

rcycle ( $count )

The opposite of cycle.
