NAME

Role::TinyCommons::Tree::FromObjArray - Role that provides methods to build a tree of objects from a nested array of objects

VERSION

This document describes version 0.126 of Role::TinyCommons::Tree::FromObjArray (from Perl distribution Role-TinyCommons-Tree), released on 2021-05-06.

MIXED IN ROLES

Role::TinyCommons::Tree::NodeMethods

PROVIDED METHODS

new_from_obj_array($obj_array) => obj

Construct a tree of objects from a nested array of objects $obj_array. The array must contain the root node object followed by zero or more children node objects. Each child can be directly followed by an arrayref to specify its children. Examples:

[$root_node_obj]                                     # if there are no children nodes

[$root_node_obj, [$child1_obj, $child2_obj]]         # if root node has two children

[$root_node_obj, [
  $child1_obj, [$grandchild1_obj, $grandchild2_obj],
  $child2_obj]]                                      # if first child has two children of its own

A more complex example ($ABC, $DEF, and so on are all objects):

[$ABC, [
  $DEF, [$GHI, $JKL],
  $MNO, [$PQR, [$STU]],
  $VWX
 ]]

The above tree can be visualized as follow:

$ABC
  ├─$DEF
  │   ├─$GHI
  │   └─$JKL
  ├─$MNO
  │   └─$PQR
  │       └─$STU
  └─$VWX

The objects will be connected to each other by calling their parent() and children() methods. See Role::TinyCommons::Tree::Node for more details.
