The directory receiver is the consumer supplied interface for receiving notifications pertaining to new, updated or deleted directories.

An example showing how to receive notifications of new directories created under a user's home directory.

notificationSession = manager.getDirectoryNotificationSessionForDirectory(myReceiver, "/Users/tom");
notificationSession.useFederatedDirectoryView();
notificationSession.registerForNewDirectories();
                

class myReceiver {
    void newDirectories(osid.id.IdList directoryIds) {
        while (directoryIds.hasNext()) {
           osid.filing.Directory directory = lookupSession.getDirectory(directoryIds.getNextId());
           print "new directory created: " + directory.getPath());
        }

        notificationSession.acknowledgeDiectoryNotification(notificationId);
    }

    void changedDirectories(osid.id.IdList directoryIds) {}
    void deletedDirectories(osid.id.IdList directoryIds) {}
    void up() {}
    void down() {}
}
