virtual void loadRawDataContainer (const String &filename, RawDataContainer &output, const String &resourceGroup)=0
 Load XML data using InputSource objects.
virtual void unloadRawDataContainer (RawDataContainer &data)
 Unload raw binary data. This gives the resource provider a change to unload the data in its own way before the data container object is destroyed. If it does nothing, then the object will release its memory.
