NAME

Array::Iterator::Reusable - A subclass of Array::Iterator to allow reuse of iterators

VERSION

This document describes version 0.131 of Array::Iterator::Reusable (from Perl distribution Array-Iterator), released on 2021-09-26.

SYNOPSIS

  use Array::Iterator::Reusable;

  # create an iterator with an array
  my $i = Array::Iterator::Reusable->new(1 .. 100);

  # do something with the iterator
  my @accumulation;
  push @accumulation => { item => $iterator->next() } while $iterator->has_next();

  # now reset the iterator so we can do it again
  $iterator->reset();

DESCRIPTION

Sometimes you don't want to have to throw out your iterator each time you have exhausted it. This class adds the "reset" method to allow reuse of an iterator. This is a very simple addition to the Array::Iterator class of a single method.

METHODS

This is a subclass of Array::Iterator, only those methods that have been added are documented here, refer to the Array::Iterator documentation for more information.

reset: This resets the internal counter of the iterator back to the start of the array.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
