|
-- OBJECTIVE:
|
27 |
|
|
-- Check that a child unit can raise an exception that is declared in
|
28 |
|
|
-- parent.
|
29 |
|
|

|
30 |
|
|
-- TEST DESCRIPTION:
|
31 |
|
|
-- Declare a package which defines complex number abstraction with
|
32 |
|
|
-- user-defined exceptions (foundation code).
|
33 |
|
|
--
|
34 |
|
|
-- Add a public child package to the above package. Declare two
|
35 |
|
|
-- subprograms for the parent type. Each of the subprograms raises a
|
36 |
|
|
-- different exception, based on the value of an input parameter.
|
37 |
|
|
--
|
38 |
|
|
-- Add a public child procedure to the foundation package. This
|
39 |
|
|
-- procedure raises an exception based on the value of an input
|
40 |
|
|
-- parameter.
|
41 |
|
|
--
|
42 |
|
|
-- Add a public child function to the foundation package. This
|
43 |
|
|
-- function raises an exception based on the value of an input
|
44 |
|
|
-- parameter.
|
45 |
|
|
--
|
46 |
|
|
-- In the main program, "with" the child packages, then check that
|
47 |
|
|
-- the exceptions are raised and handled as expected. Ensure that
|
48 |
|
|
-- exceptions are:
|
49 |
|
|
-- 1) raised in the public child package and handled/reraised to
|
50 |
|
|
-- be handled by the main program.
|
51 |
|
|
-- 2) raised and handled locally in the public child package.
|
52 |
|
|
-- 3) raised and handled locally by "others" in the public child
|
53 |
|
|
-- procedure.
|
54 |
|
|
-- 4) raised in the public child function and propagated to the
|
55 |
|
|
-- main program.
