| -- OBJECTIVE: |
| -- Check that class-wide objects can be initialized using allocation. |
| -- |
| -- TEST DESCRIPTION: |
| -- Declare access types that refer to class-wide types, one with basis |
| -- of the root type, another with basis of a type extended from the root. |
| -- Declare objects of these access types, and allocate class-wide |
| -- objects, initialized to values of specific types within the particular |
| -- classes. |
| -- |
| -- The particular root and extended types used in this abstraction are |
| -- defined in foundation code (F341A00.A), and are graphically displayed |
| -- as follows: |
| -- |
| -- package Bank |
| -- type Account |
| -- | |
| -- | |
| -- | |
| -- package Checking |
| -- type Account |
| -- | |
| -- | |
| -- | |
| -- package Interest_Checking |
| -- type Account |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
| -- |
| -- F341A00.A |
| -- |
| -- The following files comprise this test: |
| -- |
| -- => C341A04.A |
