KFileItemModelRolesUpdater: Avoid multiple updates for Nepomuk data
Review Request #108543 - Created Jan. 22, 2013 and submitted
KFileItemModelRolesUpdater: Avoid multiple updates for Nepomuk data The Nepomuk ResourceWatcher emits 3 signals - propertyChanged, propertyAdded and propertyRemoved. We should only listen to either the propertyChanged signal or the propertyAdded + Removed signals. There is no point in listening to all 3 signals. That will just result in unnecessary updates. Additionally, we do not need to listen to the resourceCreated signal. That is only emitted when we are watching for a specific types, which we are not.
Updates work as expected.
