26 -- OBJECTIVE:
27 -- Check that a nonprivate tagged type declared in a package specification
28 -- may be extended with a record extension in a different package
29 -- specification, and that this record extension may in turn be extended
30 -- by a private extension in a third package.
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 record 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.
54 --
55 -- Extend the extension with a private extension in a third package
56 -- specification. Declare a new primitive subprogram for this private
57 -- extension, and override one of the three inherited subprograms.
58 -- Within the overriding subprogram, utilize type conversion to call the
59 -- parent's implementation of the same subprogram. Also within the
60 -- overriding subprogram, call the new primitive subprogram and each
61 -- inherited subprogram.
62 --
63 -- Also in the third package, declare two operations of the private
64 -- extension which utilize aggregates and equality operators to verify
65 -- the correctness of the components.
66 --
67 -- In the main program, declare objects of the two extended types.
68 -- For each object, call the overriding subprogram, and verify the
69 -- correctness of the components by using aggregates and equality
70 -- operators, or by checking the components directly, or, for the private
71 -- extension, by calling the verification operations declared in the
72 -- third package.
