+/**
+  * 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.
