-- FOUNDATION DESCRIPTION:
-- This foundation declares a hierarchy of tagged types, which includes
-- both abstract and non-abstract types, and which have both abstract
-- and non-abstract primitive subprograms.
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 03 Nov 95 SAIC ACVC 2.0.1 fixes: Deleted primitive operation Proc
-- of Concrete_Root.
-- 11 Aug 96 SAIC ACVC 2.1: Changed procedure bodies to update
-- actual parameters.
--
--!
package FC51C00 is
--
-- Non-abstract ultimate ancestor type:
--
type Concrete_Root is tagged null record;
function Func (P: Concrete_Root) return Concrete_Root; -- Abstract when
-- inherited.
--
-- Abstract descendant of non-abstract ultimate ancestor:
--
type Abstract_Child is abstract new Concrete_Root with null record;
-- Inherits:
-- function Func (P: Abstract_Child) return Abstract_Child is abstract;
procedure Proc (P: in out Abstract_Child) is abstract; -- Abstract.
procedure New_Proc (P : out Abstract_Child) is abstract; -- Abstract.
--
-- Non-abstract descendant of abstract descendant:
--
type Concrete_GrandChild is new Abstract_Child with null record;
function Func (P: Concrete_GrandChild) return Concrete_GrandChild;
procedure Proc (P: in out Concrete_GrandChild);
procedure New_Proc (P : out Concrete_GrandChild);
