| * {@code OBJECT_REMOVED}. |
| *<p> |
| * Such a listener must: |
| *<ol> |

| *<li>Implement {@code NamingListener.namingExceptionThrown()} so that |

| * collect information about the events. |
| *<li>Register with the source using the source's {@code addNamingListener()} |
| * method. |
| *</ol> |
| * A listener that wants to be notified of {@code OBJECT_CHANGED} event types |
| * should also implement the {@code ObjectChangeListener} |
| * interface. |
