Hi gt2 user. It's my first post !
I've a strange warning from QueryData when i make two or much simple
request.
please look at simple code bellow:
12 avr. 2007 16:11:46 org.geotools.data.jdbc.QueryData finalize
GRAVE: There's code leaving readers, writers or iterators unclosed (you
got an unclosed QueryData object, which is usually held by a reader or a
writer).
Call reader/writer.close() or FeatureCollection.close(iterator) after
using them to ensure they do not hold state such as JDCB connections.
QueryData was open against feature type: parcelles_polygon
It's important ? how to stop this ? I think i close my iterator so what
is the problem ?
Thanks.
Please excuse my English I'm a French student.
public class Test {
public static Feature retrive(int id) {
FeatureIterator fi = null;
FeatureCollection fc = null;
try {
PostgisDataStoreFactory pdsf = new PostgisDataStoreFactory();
PostgisDataStore dataStore = (PostgisDataStore) pdsf
.createDataStore(conect.getParamAsMap());
FeatureSource fs =
dataStore.getFeatureSource("parcelles_polygon");
// Create the id filter
FilterFactory2 ff = (FilterFactory2) CommonFactoryFinder
.getFilterFactory(null);
Filter selectFid =
ff.id(Collections.singleton(ff.featureId("parcelles_polygon"
+ "." + id)));
// get the filtered collection
fc = fs.getFeatures(selectFid);
fi = fc.features();
//test if the feature exist
if ((fc == null)) {
return null;
} else {
if (fc.isEmpty()) {
return null;
}
}
fi = fc.features();
return fi.next();
} catch (IOException e) {
LOGGER.warning("DataBase not found: " + e.getLocalizedMessage()
+ " exit");
System.exit(1);
} finally {
if (fi != null)
fi.close();
if (fc != null) {
fc.close(fi);
}
}
return null;
}
public static void main(String[] args) {
System.out.println(retrive(123));
System.out.println(retrive(12));
}
