Example 2 with PersistentMap

use of com.oath.cyclops.types.persistent.PersistentMap in project cyclops by aol.

the class PersistentMapSerializer method serialize.

@Override
public void serialize(PersistentMap<?, ?> value, JsonGenerator gen, SerializerProvider serializers) throws IOException {
    if (value.iterator().hasNext()) {
        Tuple2<?, ?> keyAndValue = value.iterator().next();
        MapType type = TypeFactory.defaultInstance().constructMapType(Map.class, keyAndValue._1().getClass(), keyAndValue._2().getClass());
        serializers.findTypedValueSerializer(type, true, null).serialize(value.mapView(), gen, serializers);
    } else {
        serializers.findValueSerializer(Map.class).serialize(new HashMap<>(), gen, serializers);
    }
}
