        JSONObject

      • getGenericJSONEncoding

        public static JSONEncoding<? extends java.util.Map,? extends java.util.List> getGenericJSONEncoding()
        Create a JSONEncoding instance that supports conversion of tuples and attribute values into JSON data structures using standard collection types java.util.Map and java.util.List. This can be used to interface with JSON libraries whose object and array types do not implement Map or List, such as google-gson. Library specific code must be written to convert the JSON Map objects that represent tuples into the library's JSON object representation.
        Returns:
        A JSONEncoding instance.

        public static <O extends java.util.Map,A extends java.util.List> JSONEncoding<O,A> newJSONEncoding(java.lang.Class<O> jsonObjectClass,
                                                                                   java.lang.Class<A> jsonArrayClass)
        Create a JSONEncoding instance that supports conversion of tuples and attribute values into JSON data structures using JSON library types that extend standard collection types java.util.Map and java.util.List.
        Returns:
        A new JSONEncoding instance.
