Hello Manisharai,
Take a look at the following classes: DataStore, FeatureSource and
FeatureIterator.
Following extract is based on GT 8, but the basic approach will be the same
for newer versions.
File file = ...
FileDataStore store = FileDataStoreFinder.getDataStore(file);
FeatureSource<SimpleFeatureType, SimpleFeature> featureSource =
dataStore.getFeatureSource(store.getTypeNames()[0]);
SimpleFeatureIterator iterator = featureSource.getFeatures().features();
try {
while(iterator.hasNext()){
SimpleFeature feature = iterator.next();
Geometry geometricObject = feature.getAttribute(0);
Polygon polygon = (Polygon) geometricObject;
// Do things with polygon
}
} finally {
iterator.close();
}
Regards,
Dieter
