SYNOPSIS


    use List::Cycle;

FUNCTIONS

new( {values => \@values} )

Sets the cycle values and resets the internal pointer.

$cycle->reset

Sets the internal pointer back to the beginning of the cycle.


    my $color = List::Cycle->new( {values => [qw(red white blue)]} );

    print $color->next; # red

    print $color->next; # white

    $color->reset;

    print $color->next; # red

$cycle->dump

Please report any bugs or feature requests to bug-list-cycle @ rt.cpan.org, or through the web interface at http://rt.cpan.org/NoAuth/ReportBug.html. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.


ACKNOWLEDGEMENTS

List::Cycle is a playground that uses some of the ideas in Damian Conway's marvelous Perl Best Practices. http://www.oreilly.com/catalog/perlbp/ One of the chapters mentions a mythical List::Cycle module, so I made it real.

Thanks also to Ricardo SIGNES for patches.
