| 23 | <p>A role method bound with the modifier <code>get</code> |
| 24 | should have no arguments |
| 25 | (it <em>may</em> have arbitrary arguments, which are silently ignored) |
| 26 | and should have a return type to which the base field is compatible. |
| 27 | A role method returning void will ignore the given value and thus has |
| 28 | no effect at all, which will be signaled by a compiler warning. |
| 29 | <br /> |
| 30 | A role method bound with the modifier <code>set</code> must have a first argument |
| 31 | that is compatible to the base field's type (additional arguments - if present - |
| 32 | are silently ignored) and must not declare a return type. |
