Examples of NamespaceEvent

javanet.staxutils.events.NamespaceEvent
{@link Namespace} event implementation. @author Christian Niles @version $Revision: 1.3 $
org.apache.hadoop.hdfs.notifier.NamespaceEvent
Emitted when an operation in the HDFS namespace occured. If a client subscribed to the server for a particular event, a notification (see NamespaceNotification) will be sent.
