NAME

Role::TinyCommons::Collection::GetItemByPos - Locating an item by an integer position

VERSION

This document describes version 0.010 of Role::TinyCommons::Collection::GetItemByPos (from Perl distribution Role-TinyCommons-Collection), released on 2024-01-16.

SYNOPSIS

DESCRIPTION

This role is for ordered collections that support locating an item via an integer position (0 is the first, 1 the second and so on). Arrays are example of such collections. This operation is a more specific type of getting an item by key (see Role::TinyCommons::Collection::GetItemByKey).

REQUIRED METHODS

get_item_at_pos

Usage:

my $item = $obj->get_item_at_pos($pos); # dies when not found

Return item at position $pos (0-based integer). Method must die when there is no item at such position.

has_item_at_pos

Usage:

my $has_item = $obj->has_item_at_pos($pos); # => bool

Check whether the collection has item at position $pos.

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, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
