Heap::Elem::Str - phpMan

NAME
    Heap::Elem::Str - String Heap Elements

SYNOPSIS
      use Heap::Elem::Str( StrElem );
      use Heap::Fibonacci;

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

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

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

DESCRIPTION
    Heap::Elem::Str is used to wrap string 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::StrRev 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.
