| 28 | +/** | |
| 29 | + * Specifies the method that a listener of a <tt>NamingEvent</tt> | |
| 30 | + * with event type of <tt>OBJECT_CHANGED</tt> must implement. | |
| 31 | + *<p> | |
| 32 | + * An <tt>OBJECT_CHANGED</tt> event type is fired when (the contents of) | |
| 33 | + * an object has changed. This might mean that its attributes have been modified, | |
| 34 | + * added, or removed, and/or that the object itself has been replaced. | |
| 35 | + * How the object has changed can be determined by examining the | |
| 36 | + * <tt>NamingEvent</tt>'s old and new bindings. | |
| 37 | + *<p> | |
| 38 | + * A listener interested in <tt>OBJECT_CHANGED</tt> event types must: | |
| 39 | + *<ol> | |
| 40 | + * | |
| 41 | + *<li>Implement this interface and its method (<tt>objectChanged()</tt>) | |
| 42 | + *<li>Implement <tt>NamingListener.namingExceptionThrown()</tt> so that | |
| 43 | + * it will be notified of exceptions thrown while attempting to | |
| 44 | + * collect information about the events. | |
| 45 | + *<li>Register with the source using the source's <tt>addNamingListener()</tt> | |
| 46 | + * method. | |
| 47 | + *</ol> | |
| 48 | + * A listener that wants to be notified of namespace change events | |
| 49 | + * should also implement the <tt>NamespaceChangeListener</tt> | |
| 50 | + * interface. | |
