Forest::Tree - An n-ary tree
use Forest::Tree; my $t = Forest::Tree->new( node => 1, children => [ Forest::Tree->new( node => 1.1, children => [ Forest::Tree->new(node => 1.1.1), Forest::Tree->new(node => 1.1.2), Forest::Tree->new(node => 1.1.3), ] ), Forest::Tree->new(node => 1.2), Forest::Tree->new( node => 1.3, children => [ Forest::Tree->new(node => 1.3.1), Forest::Tree->new(node => 1.3.2), ] ), ] ); $t->traverse(sub { my $t = shift; print((' ' x $t->depth) . ($t->node || '\undef') . "\n"); });
This module is a basic n-ary tree, it provides most of the functionality of Tree::Simple, whatever is missing will be added eventually.
This class inherits from Forest::Tree::Pure>, but all shared methods and attributes are documented in both classes.
This variant will not clone the parent, but return a clone of the subtree that is detached.
Equivalent to calling "$tree-"parent->get_child_index($tree)>.
Returns -1 if the node has no parent (the root node).
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
