NAME

6       Heap::Elem::Str - String Heap Elements
7

SYNOPSIS

9         use Heap::Elem::Str( StrElem );
10         use Heap::Fibonacci;
11
12         my $heap = Heap::Fibonacci->new;
13         my $elem;
14
15         foreach $i ( 'aa'..'bz' ) {
16             $elem = StrElem( $i );
17             $heap->add( $elem );
18         }
19
20         while( defined( $elem = $heap->extract_top ) ) {
21             print "Smallest is ", $elem->val, "\n";
22         }
23

DESCRIPTION

25       Heap::Elem::Str is used to wrap string values into an element that can
26       be managed on a heap.  The top of the heap will have the smallest
27       element still remaining.  (See Heap::Elem::StrRev if you want the heap
28       to always return the largest element.)
29
30       The details of the Elem interface are described in Heap::Elem.
31
32       The details of using a Heap interface are described in Heap.
