示例1: reprojectFilter

private Query reprojectFilter(Query query) throws IOException {
SimpleFeatureType nativeFeatureType = source.getSchema();
final GeometryDescriptor geom = nativeFeatureType.getGeometryDescriptor();
// if no geometry involved, no reprojection needed
if(geom == null)
return query;

// default CRS: the CRS we can assume geometry and bbox elements in filter are
// that is, usually the declared one, but the native one in the leave case
CoordinateReferenceSystem defaultCRS = null;
// we need to reproject all bbox and geometries to a target crs, which is
// the native one usually, but it's the declared on in the force case (since in
// that case we completely ignore the native one)
