statistics method

Implementation

void statistics() {
  int poiCount = _poiinfos.values.fold(0, (int combine, Poiinfo poiinfo) => combine + poiinfo.count);
  int wayCount = _wayinfos.values.fold(0, (combine, wayinfo) => combine + wayinfo.wayCount);
  int pathCount =
      _wayinfos.values.fold(0, (combine, wayinfo) => combine + wayinfo.wayholders.fold(0, (combine, wayholder) => combine + wayholder.pathCount()));
  int nodeCount = _wayinfos.values.fold(0, (combine, wayinfo) => combine + wayinfo.nodeCount);
  _log.info(
      "$zoomlevelRange, baseZoomLevel: $baseZoomLevel, tiles: $tileCount, poi: $poiCount, way: $wayCount with ${wayCount != 0 ? (pathCount / wayCount).toStringAsFixed(1) : "n/a"} paths and ${pathCount != 0 ? (nodeCount / pathCount).toStringAsFixed(1) : "n/a"} nodes per path");
