| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that a variable object of an indefinite type is properly |
| -- initialized/constrained by an initial value assignment that is |
| -- a) an aggregate, b) a function, or c) an object. Check that objects |
| -- of the above types do not need explicit constraints if they have |
| -- initial values. |
| -- |
| -- TEST DESCRIPTION: |
| -- An indefinite subtype is either: |
| -- a) An unconstrained array subtype. |
| -- b) A subtype with unknown discriminants. |
| -- c) A subtype with unconstrained discriminants without defaults. |
| -- |
| -- Declare several indefinite types in a parent package specification. |
| -- In the private part, complete one type with a discriminant without |
| -- default (indefinite) and the other with a default discriminant |
| -- (definite). Declare objects of both indefinite and definite subtypes |
| -- in children (private and public) with initialization expressions. The |
| -- test verifies all values of the objects. It also verifies that |
| -- Constraint_Error is raised if an attempt is made to change the |
| -- discriminants of the objects of the indefinite subtypes. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 15 Jan 95 SAIC Initial version for ACVC 2.1 |
| -- 25 Jul 96 SAIC Modified test description. Deleted use C330001_0. |
| -- 20 Nov 98 RLB Added Elaborate pragmas to avoid problems |
| -- with an unconventional, but legal, elaboration |
| -- order. |
