Heap::Elem::Ref - Object Reference Heap Elements SYNOPSIS
use Heap::Elem::Ref( RefElem ); use Heap::Fibonacci; my $heap = Heap::Fibonacci->new; my $elem; foreach $i ( 1..100 ) { $obj = myObject->new( $i ); $elem = RefElem( $obj ); $heap->add( $elem ); } while( defined( $elem = $heap->extract_top ) ) { # assume that myObject object have a method I<printable> print "Smallest is ", $elem->val->printable, " "; } DESCRIPTION
Heap::Elem::Ref is used to wrap object reference values into an element that can be managed on a heap. Each referenced object must have a method cmp which can compare itself with any of the other objects that have references on the same heap. These comparisons must be consis- tant with normal arithmetic. The top of the heap will have the smallest (according to cmp) element still remaining. (See Heap::Elem::RefRev if you want the heap to always return the largest element.) The details of the Elem interface are described in Heap::Elem. The details of using a Heap interface are described in Heap. AUTHOR
