tileFilter()

virtual FilterHandle tileFilter ( )

pure virtual

Speed-up: inspect the bounding box and attribute statistics of each tile before it is loaded and processed. Skip tiles for which surely none of their points pass this filter. The returned filter is usually the same as the filter used internally by the kernel to decide if a point shall be processed. If all tiles shall be processed, return an empty handle.
