Here's one way that you might do it...
public void checkParcel(SimpleFeature parcel, FeatureSource buildings) {
FilterFactory2 filterFactory =
CommonFactoryFinder.getFilterFactory2(null);
Geometry parcelGeom = (Geometry) parcel.getDefaultGeometry();
Filter withinFilter = filterFactory.within(
filterFactory.property("the_geom"),
filterFactory.literal(parcelGeom));
try {
FeatureCollection buildingsInParcel =
buildings.getFeatures(withinFilter);
if (buildingsInParcel.isEmpty()) {
System.out.println("parcel does not contain any buildings");
} else {
System.out.println("parcel has these buildings...");
FeatureIterator iter = buildingsInParcel.features();
try {
SimpleFeature building = (SimpleFeature) iter.next();
// print out info about building...
} catch (Exception ex) {
// do something
} finally {
iter.close();
}
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
Hope this helps,
Michael
