NAME

Heap::Elem::Num - Perl extension for Numeric Heap Elements

SYNOPSIS

use Heap::Elem::Num( NumElem );
use Heap::Fibonacci;

my $heap = Heap::Fibonacci->new;
my $elem;

foreach $i ( 1..100 ) {
    $elem = NumElem( $i );
    $heap->add( $elem );
}

while( defined( $elem = $heap->extract_minimum ) ) {
    print "Smallest is ", $elem->val, "\n";
}

DESCRIPTION

Heap::Elem::Num is used to wrap numeric values into an element that can be managed on a heap. The top of the heap will have the smallest element still remaining. (See Heap::Elem::NumRev 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.
