NAME
   Role::TinyCommons::Tree - Roles related to object tree

VERSION
   This document describes version 0.124 of Role::TinyCommons::Tree (from
   Perl distribution Role-TinyCommons-Tree), released on 2020-04-14.

DESCRIPTION
   This distribution provides several roles you can use to create a tree
   class. The roles are designed for maximum reusability and minimum
   clashes with your existing class.

   To create a tree class, all you need to do is apply the
   Role::TinyCommons::Tree::Node role:

    use Role::Tiny::With;
    with 'Role::TinyCommons::Tree::Node';

   The Tree::Node common role just requires you to have two methods:
   "parent" (which should return parent node object) and "children" (which
   should return a list or arrayref of children node objects).

   Utility methods such as "descendants", "walk", "is_first_child" and so
   on are separated to Role::TinyCommons::Tree::NodeMethods which you can
   apply if you want.

   The actual methods in Role::TinyCommons::Tree::NodeMethods are actually
   implemented in Code::Includable::Tree::NodeMethods, so you can import
   them to your class manually or just call the routines as a normal
   function call if you do not want to involve Role::Tiny. See an example
   of this usage in Data::CSel.
