| <p>Lifting uses a default constructor which takes exactly one argument of the type |
| of the declared base class (after <code>playedBy</code>). |
| By default the compiler generates such a constructor for each bound role. |
| On the other hand, default constructors that take no arguments |
| (as in <a href="http://java.sun.com/docs/books/jls/second_edition/html/classes.doc.html#16823" |
| class="ext">JLS §8.8.7</a>) are never generated for bound roles. |
| <br /> |
| The super-constructor to be invoked by a default lifting constructor |
| depends on whether the role's super class is a bound role or not. |
| |
| </p> |
| <ul> |
| <li>If the super-class is a bound role, the default lifting constructor will invoke the default lifting constructor of the super-class.</li> |
| <li>If the super-class is not a bound role, the default lifting constructor will invoke the normal argumentless default constructor |
| of the super-class. |
| </li> |
| </ul> |
