NAME

Role::TinyCommons::Collection::PickItems::Iterator - Provide pick_items() from a resettable iterator

VERSION

This document describes version 0.006 of Role::TinyCommons::Collection::PickItems::Iterator (from Perl distribution Role-TinyCommons-Collection), released on 2021-05-03.

DESCRIPTION

This role provides pick_items() that picks random items by doing a one-time full scan (or iteration) of a resettable iterator.

Note that for a huge collection, this might not be a good idea. If your collection support get_item_at_pos and an efficient get_item_count, you can use Role::TinyCommons::FindItems::RandomSeek.
