| -- |
| -- OBJECTIVE: |
| -- Check that a nonprivate tagged type declared in a package specification |
| -- may be extended with a record extension in a different package |
| -- specification, and that this record 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 predefined equality operators are defined for the tagged |
| -- type and its derivatives. |
| -- |
| -- 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 type and two associated primitive subprograms |
| -- in a package specification (foundation code). |
| -- |
| -- Extend the root type with a record extension in a different 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. |
| -- |
| -- 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. |
| -- |
| -- Also in the third package, declare two operations of the private |
| -- extension which utilize aggregates and equality operators to verify |
| -- the correctness of the components. |
| -- |
| -- In the main program, declare objects of the two extended types. |
| -- For each object, call the overriding subprogram, and verify the |
| -- correctness of the components by using aggregates and equality |
| -- operators, or by checking the components directly, or, for the private |
| -- extension, by calling the verification operations declared in the |
| -- third package. |
