| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that if a discriminant constraint depends on a discriminant, |
| -- the evaluation of the expressions in the constraint is deferred |
| -- until an object of the subtype is created. Check for cases of |
| -- records where the component containing the constraint is present |
| -- in the subtype. |
| -- |
| -- TEST DESCRIPTION: |
| -- This transition test defines record types with discriminant components |
| -- which depend on the discriminants. The discriminants are calculated |
| -- by function calls. The test verifies that Constraint_Error is raised |
| -- during the object creations when values of discriminants are |
| -- incompatible with the subtypes. Also check for cases, where the |
| -- component is absent. |
| -- |
| -- Inspired by C37213E.ADA, C37213G.ADA, C37215E.ADA, and C37215G.ADA. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 10 Apr 96 SAIC Initial version for ACVC 2.1. |
| -- 14 Jul 96 SAIC Modified test description. Added exception handler |
| -- for VObj_10 assignment. |
| -- 26 Oct 96 SAIC Added LM references. |
