NAME
LinkedList::Single::Example::Probe - payload object that records when it is destroyed
SYNOPSIS
use LinkedList::Single::Example::Probe;
LinkedList::Single::Example::Probe->reset;
$window->record( $time, LinkedList::Single::Example::Probe->new( $id ) );
my @ids = LinkedList::Single::Example::Probe->destroyed;
DESCRIPTION
A linked list releases each node as soon as nothing refers to it. That is hard to see from the outside; these objects make it visible by noting their id when perl destroys them. The examples use them to show that consuming a Fragment destroys its payloads one at a time as the Fragment advances.
