| -- |
| -- OBJECTIVE: |
| -- Check that deriving abstract types from the types in Ada.Finalization |
| -- does not negatively impact the implicit operations. |
| -- Check that an object of a controlled type is finalized when the |
| -- enclosing master is complete. |
| -- Check that finalization occurs in the case where the master is |
| -- left by a transfer of control. |
| -- Check this for controlled types where the derived type has a |
| -- discriminant. |
| -- Check this for cases where the type is defined as private, |
| -- and the full type is derived from the types in Ada.Finalization. |
| -- |
| -- Check that finalization of controlled objects is |
| -- performed in the correct order. In particular, check that if |
| -- multiple objects of controlled types are declared immediately |
| -- within the same declarative part then type are finalized in the |
| -- reverse order of their creation. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test checks these conditions for subprograms and |
| -- block statements; both variables and constants of controlled |
| -- types; cases of a controlled component of a record type, as |
| -- well as an array with controlled components. |
| -- |
| -- The base controlled types used for the test are defined |
| -- with a character discriminant. The initialize procedure for |
| -- the types will record the order of creation in a globally |
| -- accessible array, the finalize procedure for the types will call |
| -- TCTouch with that tag character. The test can then check that |
| -- the order of finalization is indeed the reverse of the order of |
| -- creation (assuming that the implementation calls Initialize in |
| -- the order that the objects are created). |
