Examples of org.geotools.geojson.feature.FeatureJSON$FeatureEncoder

org.geotools.geojson.feature.FeatureJSON

Reads and writes feature objects to and from geojson.

 SimpleFeature feature = ...; FeatureJSON io = new FeatureJSON(); io.writeFeature(feature, "feature.json")); Iterator features = io.streamFeatureCollection("features.json"); while(features.hasNext()) { feature = features.next(); ... }
