| -- OBJECTIVE: |
| -- Check that primitive operations declared in a child package |
| -- override operations declared in ancestor packages, and that |
| -- operations on class-wide types defined in the ancestor packages |
| -- dispatch as appropriate to these overriding implementations. |
| -- |
| -- TEST DESCRIPTION: |
| -- |
| -- This test builds on the foundation code file (FA11C00) that contains |
| -- a parent package, child package, and grandchild package. The parent |
| -- package declares a tagged type and primitive operation. The child |
| -- package extends the type, and overrides the primitive operation. The |
| -- grandchild package does the same. |
| -- |
| -- The test procedure "withs" the grandchild package, and receives |
| -- visibility to all of its ancestor packages, types and operations. |
| -- A procedure with a formal class-wide parameter is defined that will |
| -- allow for dispatching calls to the overridden primitive operations, |
| -- based on the specific type of the actual parameter. The primitive |
| -- operations provide a string value to update a global string array |
| -- variable. Calls to the local procedure are made, with objects of each |
| -- of the tagged types as parameters, and the global variable is finally |
| -- examined to ensure that the correct version of primitive operation was |
| -- dispatched correctly. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
