José. -----Original Message----- From: christopher j bottaro [mailto:[EMAIL PROTECTED] Sent: Saturday, December 20, 2003 8:46 PM To: [EMAIL PROTECTED] Subject: deallocating? just for practice, i made a class BinaryTree. its just a blessed reference to a hash that contains two things: size and root. root gets assigned to a BinaryTree::Node which is just a bless reference containing: key, value, left, right. perl deallocates according to reference counts. so if i want "destory" my tree structure, i'd have to make sure there are no references to any of the BinaryTree::Node's, right? something like this... $my pr_clear; $pr_clear = sub { my $p = shift(); # parent node my $w = shift(); # which child of the parent my $n = shift(); # child node if ($n != undef) { this->$pr_clear($n, "left", $n->left()); this->$pr_clear($n, "right", $n->right()); $p->$w(undef); } } sub clear() { this->$pr_clear(this->{root}, "left", this->{root}->left()); this->$pr_clear(this->{root}, "right", this->{root}->right()); this->{root} = undef; } thanks in advance, and thanks to those who helped with the module questions, -- christopher -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response> **** DISCLAIMER **** "This e-mail and any attachment thereto may contain information which is confidential and/or protected by intellectual property rights and are intended for the sole use of the recipient(s) named above.
