Hi,
I just want to create a geometry from a WFS query.
I make a WFS query and send it to WFS server, which returns me the
requested features.
I save the result in a XML file temporary. it has the geometry inside as well.
I can read all the numerical data from the file as follows:
tmp = File.createTempFile("getFeature", "xml");
tmp.deleteOnExit();
Transformer tx = TransformerFactory.newInstance().newTransformer();
tx.transform(new DOMSource(doc), new StreamResult(tmp));
in = new FileInputStream(tmp);
WFSConfiguration configuration = new org.geotools.wfs.v1_1.WFSConfiguration();
Parser parser = new Parser(configuration);
FeatureCollectionType fc = (FeatureCollectionType) parser.parse(in);
EList featureCollections = fc.getFeature();
assert featureCollections.size() <= 1 : "feature
collection size should only be zero or one";
SimpleFeatureCollection featureCollection =
(SimpleFeatureCollection) featureCollections
.get(0);
LOGGER.debug("There are " + featureCollection.size()
+ " featureCollection entries.");
SimpleFeatureIterator features = featureCollection.features();
while (features.hasNext()) {
SimpleFeature f = features.next();
Map<String, Object> featureMap = new HashMap<String, Object>();
for (String attribute : attributesToReturn) {
Object attributeValue = f.getAttribute(attribute);
featureMap.put(attribute, attributeValue);
}
// the row (or Map in this case) will use the attribute value of
// the table linking key as its key. we'll assume here that
// the table linking key is always provided as one of the
// parameters in the attributesToBeReturned field
Object fid = f.getAttribute(params.getTableLinkingKey());
// think of an entry in the featureMembers map being a row
// in a table and the featureMap being the column entries
// for each row
featureMembers.put(fid, featureMap);
}
}
but in this case I see the geometry field is empty.
I wonder if anyone knows how to handle the geometry.
Do I need the GML parser?
Thanks in advance,
Bahman
