- * pseudo interface. It returns this object (therefore we implement

- * - The DownloadsPlacesView object adds itself as a places result observer and

- * placeNodeAnnotationChanged from its callbacks.

- * @param [optional] aPlacesNode
- * The places node for a past download. Required if aDataItem is not set.
