--  Bubblesort generic package using formal procedures
 
--  This package provides a generic bubble sort routine that can be used with
--  different types of data.
 
--  See also GNAT.Bubble_Sort, a version that works with subprogram access
--  parameters, allowing code sharing. The generic version is slightly more
--  efficient but does not allow code sharing and has an interface that is
--  more awkward to use.
 
--  There is also GNAT.Bubble_Sort_A, which is now considered obsolete, but
--  was an older version working with subprogram parameters. This version
--  is retained for backwards compatibility with old versions of GNAT.
 
generic
   --  The data to be sorted is assumed to be indexed by integer values from
   --  1 to N, where N is the number of items to be sorted. In addition, the
   --  index value zero is used for a temporary location used during the sort.
 
   with procedure Move (From : Natural; To : Natural);
   --  A procedure that moves the data item with index value From to the data
   --  item with index value To (the old value in To being lost). An index
   --  value of zero is used for moves from and to a single temporary location
   --  used by the sort.
 
   with function Lt (Op1, Op2 : Natural) return Boolean;
   --  A function that compares two items and returns True if the item with
   --  index Op1 is less than the item with Index Op2, and False if the Op2
   --  item is greater than or equal to the Op1 item.
 
package GNAT.Bubble_Sort_G is
   pragma Pure;
 
   procedure Sort (N : Natural);
   --  This procedures sorts items in the range from 1 to N into ascending
   --  order making calls to Lt to do required comparisons, and Move to move
   --  items around. Note that, as described above, both Move and Lt use a
   --  single temporary location with index value zero. This sort is stable,
   --  that is the order of equal elements in the input is preserved.
 
end GNAT.Bubble_Sort_G;
