26 -- OBJECTIVE:
27 -- Check that a nonprivate tagged type declared in a package specification
28 -- may be extended with a private extension in a different package
29 -- specification, and that this private extension may in turn be extended
30 -- by a private extension.
31 --
32 -- Check that each derivative inherits the user-defined primitive
33 -- subprograms of its parent (including those that its parent inherited),
34 -- that it may override these inherited primitive subprograms, and that it
35 -- may also declare its own primitive subprograms.
36 --
37 -- Check that predefined equality operators are defined for the tagged
38 -- type and its derivatives.
39 --
40 -- Check that type conversion is defined from a type extension to its
41 -- parent, and that this parent itself may be a type extension.
42 --
43 -- TEST DESCRIPTION:
44 -- Declare a root tagged type and two associated primitive subprograms
45 -- in a package specification (foundation code).
46 --
47 -- Extend the root type with a private extension in a different package
48 -- specification. Declare a new primitive subprogram for the extension,
49 -- and override one of the two inherited subprograms. Within the
50 -- overriding subprogram, utilize type conversion to call the parent's
51 -- implementation of the same subprogram. Also within the overriding
52 -- subprogram, call the new primitive subprogram and each inherited
53 -- subprogram. Declare operations of the private extension which utilize
54 -- aggregates and equality operators to verify the correctness of the
55 -- components.
56 --
57 -- Extend the extension with a private extension in the same package
58 -- specification. Declare a new primitive subprogram for this second
59 -- extension, and override one of the three inherited subprograms.
60 -- Within the overriding subprogram, utilize type conversion to call the
61 -- parent's implementation of the same subprogram. Also within the
62 -- overriding subprogram, call the new primitive subprogram and each
63 -- inherited subprogram. Declare operations of the private extension
64 -- which override the verification operations of its parent. Within
65 -- these overriding operations, utilize type conversion to call the
66 -- parent's implementations of the same operations.
67 --
68 -- In the main program, declare objects of the two extended types.
69 -- For each object, call the overriding subprogram, and verify the
70 -- correctness of the components by calling the verification operations
71 -- declared in the second package.
