Sling Events - By Path

["David G." <da...@gmail.com>]

Does sling provide any mechanism to create an EventHandler that listens only on specific paths?  

Im aware that you can check the event's resource's path within the event handler's handleEvent/process and return accordingly, but that doesn't suffice.

I am trying to have the same event type handled differently depending on the resource path that originated the event.

Also, if there any way to set precedence of an event handler for an event (service.ranking) and preventing the event from being handled by subsequent event handler last list on that topic?

Thanks

Yes, you can define an event filter when you register the EventHandler, which allows you to limit the paths; for example

   props.put(EventConstants.EVENT_FILTER,
       "(path=/some/prefix/*)");

See the EventAdmin service spec in the OSGi Compendium for full details.
