| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that structures nesting discriminated records as |
| -- components in record extension are correctly supported. |
| -- Check that record extensions inherit all the visible components |
| -- of their ancestor types. |
| -- Check that discriminants are correctly inherited. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test defines a simple class hierarchy, where the final |
| -- derivations exercise the different possible "permissions" available |
| -- to a designer. Extension aggregates for discriminated types are used |
| -- to set values of these final types. The key difference between |
| -- this test and C391001 is that the types are visible, and allow the |
| -- creation of complex discriminated extension aggregates. Another |
| -- layer of derivation is present to more robustly check that the |
| -- inheritance is correctly supported. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 16 Dec 94 SAIC Removed offending parenthesis in aggregate |
| -- extensions, corrected typo: TC_MC SB TC_PC, |
| -- corrected visibility errors for literals, |
| -- added qualification for aggregate expressions |
| -- used in extension aggregates, corrected parameter |
| -- order in call to Communications.Creator |
| -- 01 MAY 95 SAIC Removed "limited" from the definition of Mil_Comm |
| -- 14 OCT 95 SAIC Fixed some value bugs for ACVC 2.0.1 |
| -- 04 MAR 96 SAIC Altered 3 overambitious extension aggregates |
| -- 11 APR 96 SAIC Updated documentation for 2.1 |
| -- 27 FEB 97 PWB.CTA Deleted extra (illegal) component association |
