Heap::Elem::Str(3)    User Contributed Perl Documentation   Heap::Elem::Str(3)

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 ele-
       ment 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.
