org.geotools.data.store.ReTypingFeatureCollection
SimpleFeatureCollection decorator which decorates a feature collection "re-typing" its schema based on attributes specified in a query. @author Justin Deoliveira, The Open Planning Project @source $URL$

            // rebuild the type and wrap the reader
            SimpleFeatureType schema = collection.getSchema();
            SimpleFeatureType target = SimpleFeatureTypeBuilder.retype(schema, query
                    .getPropertyNames());
            if (!target.equals(schema)) {
                collection = new ReTypingFeatureCollection(collection, target);
            }
        }
        return collection;
    }
