[Click] Notifiers

[Eddie Kohler]

Hi David,

You also must update your element's cast() function, so that someone 
looking for an "empty" or "full" notifier (whichever is appropriate) 
will find your ActiveNotifier.  The relevant constants are 
Notifier::FULL_NOTIFIER and Notifier::EMPTY_NOTIFIER.  Check out the 
versions in elements/standard/notifierqueue.cc and fullnotequeue.cc for 
examples.

Eddie
