* pseudo interface. It returns this object (therefore we implement
|
|
* onStateChangea and onProgressChange here).
|
|
* - The DownloadsPlacesView object adds itself as a places result observer and
|
|
* calls this object's placesNodeIconChanged, placesNodeTitleChanged and
|
|
* placeNodeAnnotationChanged from its callbacks.

*

|
* @param [optional] aDataItem
|
|
* The data item of a the session download. Required if aPlacesNode is not set
|
|
* @param [optional] aPlacesNode
