Heap::Elem::Num - Numeric Heap Elements
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_top ) ) { print "Smallest is ", $elem->val, "\n"; }
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 the Heap::Elem::NumRev manpage if you want the heap to always return the largest element.)
The details of the Elem interface are described in the Heap::Elem manpage.
The details of using a Heap interface are described in Heap.
