| /** |
| * Data structures for testing unique constraint settings |
| * on ORM Annotations. |
| * @UniqueConstraint annotation is declared at class-level with @Table, |
| * @SecondaryTable annotations and at field-level with @JoinTable annotation. |
| * |
| * The columns included in unique constraint must be non-nullable. This is |
| * recommended that the non-nullability of the column is explictly set by the |
| * user, though the implementation forces a column to non-nullable as a column |
| * is included in a unique constraint. |
