StrRev(3)

NAME

       Heap::Elem::StrRev - Perl extension for Reversed String Heap Elements

SYNOPSIS

         use Heap::Elem::StrRev( StrRElem );
         use Heap::Fibonacci;

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

         foreach $i ( 'aa'..'bz' ) {
             $elem = StrRElem( $i );
             $heap->add( $elem );
         }

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

DESCRIPTION

       Heap::Elem::StrRev is used to wrap string values into an element that
       can be managed on a heap.  The top of the heap will have the largest
       element still remaining.  (See Heap::Elem::Str if you want the heap to
       always return the smallest element.)

       The details of the Elem interface are described in Heap::Elem.

       The details of using a Heap interface are described in Heap.
