Moshi v1.0.0 Release Notes

  • 2015-09-27

    • API Change: Replaced new JsonReader() with JsonReader.of() and new JsonWriter() with JsonWriter.of(). If your code calls either of these constructors it will need to be updated to call the static factory method instead.
    • API Change: Don’t throw IOException on JsonAdapter.toJson(T). Code that calls this method may need to be fixed to no longer catch an impossible IOException.
    • Fix: the JSON adapter for Object no longer fails when encountering null in the stream.
    • New: @Json annotation can customize a field's name. This is particularly handy for fields whose names are Java keywords, like default or public.
    • New: Rfc3339DateJsonAdapter converts between a java.util.Date and a string formatted with RFC 3339 (like 2015-09-26T18:23:50.250Z). This class is in the new moshi-adapters subproject. You will need to register this adapter if you want this date formatting behavior. See it in action in the [dates example][dates_example].
    • New: Moshi.adapter() keeps a cache of all created adapters. For best efficiency, application code should keep a reference to required adapters in a field.
    • New: The Types factory class makes it possible to compose types like List<Card> or Map<String, Integer>. This is useful to look up JSON adapters for parameterized types.
    • New: JsonAdapter.failOnUnknown() returns a new JSON adapter that throws if an unknown value is encountered on the stream. Use this in development and debug builds to detect typos in field names. This feature shouldn’t be used in production because it makes migrations very difficult.
