-- Grant of Unlimited Rights
--
-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the
-- released technical data and computer software in whole or in part, in
-- any manner and for any purpose whatsoever, and to have or permit others
-- to do so.
--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that a private tagged type declared in a package specification
-- may be extended with a private extension in a different package
-- specification, and that this private extension may in turn be extended
-- by a private extension in a third package.
--
-- Check that each derivative inherits the user-defined primitive
-- subprograms of its parent (including those that its parent inherited),
-- that it may override these inherited primitive subprograms, and that it
-- may also declare its own primitive subprograms.
--
-- Check that type conversion is defined from a type extension to its
-- parent, and that this parent itself may be a type extension.
--
-- TEST DESCRIPTION:
-- Declare a root tagged private type and two associated primitive
-- subprograms in a package specification. Declare operations to verify
-- the correctness of the components. Declare operations which return
-- values of the type's private components, and which will be
-- inherited by later derivatives.
--
-- Extend the root type with a private extension in a second package
-- specification. Declare a new primitive subprogram for the extension,
-- and override one of the two inherited subprograms. Within the
-- overriding subprogram, utilize type conversion to call the parent's
-- implementation of the same subprogram. Also within the overriding
-- subprogram, call the new primitive subprogram and each inherited
-- subprogram. Declare operations of the private extension which
-- override the verification operations of its parent. Declare operations
-- of the private extension which return values of the extension's
-- private components, and which will be inherited by later derivatives.
--
-- Extend the extension with a private extension in a third package
-- specification. Declare a new primitive subprogram for this private
-- extension, and override one of the three inherited subprograms.
-- Within the overriding subprogram, utilize type conversion to call the
-- parent's implementation of the same subprogram. Also within the
-- overriding subprogram, call the new primitive subprogram and each
-- inherited subprogram. Declare operations of the private extension
-- which override the verification operations of its parent.
--
-- In the main program, declare objects of the root tagged type and
-- the two type extensions. For each object, call the overriding
-- subprogram, and verify the correctness of the components by calling
-- the verification operations.
