| --* |
| -- |
| -- 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 with private type component. |
| -- |
| -- TEST DESCRIPTION: |
| -- This transition test defines record type and incomplete 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. |
| -- |
| -- Inspired by C37214A.ADA and C37216A.ADA. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 11 Apr 96 SAIC Initial version for ACVC 2.1. |
| -- 06 Oct 96 SAIC Added LM references. Replaced "others exception" |
| -- with "unexpected exception" |
