Thanks. I learnt few things about how to make a proper patch too (should have done before), my patches are bit too crappy. I was thinking, can we use this mechanism for purposes like notifying (send an email or something like that) to the original author of the document when the document is changed ? Or is some other mechanism there for this purpose ? Best Regards, - Asiri On 7/21/07, Vincent Massol <[email protected]> wrote:
For those interested I've sent a patch for implementing a new notification mechanism.It's available here:
http://jira.xwiki.org/jira/browse/XWIKI-1522
I'd love to get feedback on this. Here's what I say in there:
" At the place where you want to register for an event:
getObservationManager().addListener(new DocumentSaveEvent("DocumentToWatch"), listener);
At the place where you want to receive for an event:
public class MyListener implements EventListener { public void onEvent(Event event, Object source, Object data) { ... } }
At the place where you want to fire notifications to event listeners:
getObservationManager().notify(new DocumentSaveEvent("SomeDocument"), "some source", "some data");
It's easily extensible and you can create all sorts of events as it's fully generic. "
Have a look at the implementation. You'll see I have even introduced the notion of EventFilter so that we can have regex when registering interest for an event.
Thanks -Vincent
