| *<BR> |
| *<B>Assertion ID:</B> A14.6.9-3. |
| *<BR> |
| *<B>Assertion Description: </B> |
| * If a variable or a field of a variable is included in the result, |
| * either directly or via navigation through the variable, |
| * then the semantics of the contains clause that include the variable change. |
| * In this case, all values of the variable |
| * that satisfy the filter are included in the result. |
| * Result expressions begin with either an instance of the candidate class |
| * (with an explicit or implicit "this") or an instance of a variable |
| * (using the variable name). The candidate tuples are the cartesian product |
| * of the candidate class and all variables used in the result. The result |
| * tuples are the tuples of the candidate class and all variables used |
| * in the result that satisfy the filter. |
| * The result is the collection of result expressions projected from the |
| * result tuples. |
| * |
| * This test differs from VariableInResult by extending the navigation |
| * of variables. It navigates from the candidate Department class to include |
| * fields in the corresponding Company. It navigates from the candidate |
| * Company class to Department, Employee, and Project. |
