Maybe someone can help me solve one final little issue.
The parallel Merge Sort works fine now. But when I want to use it I cannot
directly declare for example an integer array:
package IntSort is new SORT_PACKAGE(integer, compareInt);
use IntSort;
-- This declaration does not work when I want to use ar as a parameter in
a call to Sort.
ar : integer array(1..3);
-- Instead I have to use this.
ar : IntSort.element_array(1.. 3);
sort(ar);
This is the declaration of the package:
generic
type element_type is private;
with function "<=" (element1, element2 : element_type) return Boolean;
package SORT_PACKAGE is
type element_array is array(integer range <>) of element_type;
procedure Sort(InArray : in out element_array);
< ... >
end SORT_PACKAGE;
I figured that since 'type' creates a new type, which cannot be interchanged
(?) with the original type I would have to use Subtype instead.
Unfortunately the compiler won't accept...
It's only a minor issue but if you want to do it right...
Does anybody know if it's possible??
