--  Bubblesort using access to procedure parameters
33
 
34
--  This package provides a bubble sort routine that works with access to
35
--  subprogram parameters, so that it can be used with different types with
36
--  shared sorting code. It is considered obsoleted by GNAT.Bubble_Sort which
37
--  offers a similar routine with a more convenient interface.
38
 
39
package GNAT.Bubble_Sort_A is
40
   pragma Preelaborate;
41
 
42
   --  The data to be sorted is assumed to be indexed by integer values from
43
   --  1 to N, where N is the number of items to be sorted. In addition, the
44
   --  index value zero is used for a temporary location used during the sort.
45
 
46
   type Move_Procedure is access procedure (From : Natural; To : Natural);
47
   --  A pointer to a procedure that moves the data item with index From to
48
   --  the data item with index To. An index value of zero is used for moves
49
   --  from and to the single temporary location used by the sort.
50
 
51
   type Lt_Function is access function (Op1, Op2 : Natural) return Boolean;
52
   --  A pointer to a function that compares two items and returns True if
53
   --  the item with index Op1 is less than the item with index Op2, and False
54
   --  if the Op2 item is greater than or equal to the Op1 item.
55
 
56
   procedure Sort (N : Natural; Move : Move_Procedure; Lt : Lt_Function);
57
   --  This procedures sorts items in the range from 1 to N into ascending
58
   --  order making calls to Lt to do required comparisons, and Move to move
59
   --  items around. Note that, as described above, both Move and Lt use a
60
   --  single temporary location with index value zero. This sort is not
61
   --  stable, i.e. the order of equal elements in the input is not preserved.
