| /** |
| * Specifies the method that a listener of a {@code NamingEvent} |
| * with event type of {@code OBJECT_CHANGED} must implement. |
| *<p> |
| * An {@code OBJECT_CHANGED} event type is fired when (the contents of) |
| * an object has changed. This might mean that its attributes have been modified, |
| * added, or removed, and/or that the object itself has been replaced. |
| * How the object has changed can be determined by examining the |
| * {@code NamingEvent}'s old and new bindings. |
| *<p> |
| * A listener interested in {@code OBJECT_CHANGED} event types must: |
| *<ol> |
| * |
| *<li>Implement this interface and its method ({@code objectChanged()}) |
| *<li>Implement {@code NamingListener.namingExceptionThrown()} so that |
| * it will be notified of exceptions thrown while attempting to |
| * 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 namespace change events |
| * should also implement the {@code NamespaceChangeListener} |
| * interface. |
