  SpatialExtent and Count can be derived from the RTree and Datadb without needing a full table scan. This optimization can be a huge performance improvement if the caller wants to find out the extent and the number of objects for a given class. This optimization is only valid if no filter, no grouping fitler, and only the extent and count is selected.
