Description: ------------ With my implementation into HTML_Progress2, i've replaced my old one by the Event_Dispatcher, and try to keep old features. These ones are: - add/update an observer (it's possible with Event_Dispatcher 0.9.1) - remove an observer (it's possible with Event_Dispatcher 0.9.1) - retrieve the list of all observers currently attached to a dispatcher (it's not yet implemented in version 0.9.1) I expect by a such function ( probably call getObservers() ) retrieve the data(callback, class-filter) behind the $_ro (Registered observer callbacks). And why not, the notification class used ( default is Event_Notification ). But it could be overloaded by a custom one: see setNotificationClass() where there is again no reading interface. If it's not enough clear (sorry: my bad english), feel free to ask me again regards Laurent Laville

I am just repeating here what I told you privately before (in English this time :) ). You don't need to know who is listening to your notifications. Just post them and forget (Post & Forgetâ„¢), that's the way it works. So unless, you provide a good case example, I think your request will be ignored for now. Sorry.

As discussed on pear-dev, I added two new methods to CVS: - observerRegistered() - getObservers() However the second method will *not* return the actual observers, but an array of string representations.
