| /** |
| * Marks a getter for an inspectable node's inspectable children. |
| * |
| * This annotation can be applied to any getter that returns a collection of objects, either an |
| * array, an {@link Iterable} or a {@link java.util.Iterator}. The getter may return null, which |
| * will be treated as an empty collection. Additionally, the inspector will discard any null |
| * entries in the collection. |
| * |
| * By default, this annotation is inherited. At runtime, the inspector introspects on the class |
| * hierachy and uses the annotated getter from the bottommost class, if different from any |
| * annoated getters of the parent class. If a class inherits from a parent class with an annotated |
| * getter, but does not include this annotation, the child class will be traversed using the |
| * getter annotated on the parent. This holds true even if the child class overrides the getter. |
