Support for record types in JDK 14

[FrauBoes]

Hi,

I work on the JDK, and I’m curious if you are planning to support record types in JDK 14? If so, I’d be happy to help.

From a runtime reflection point of view, Java 14 added two specific methods to support records:

1. Class::isRecord
2. Class::getRecordComponents (and its j.l.r.RecordComponent type)
   It is with these two primitives that the whole Java Serializable record support is built upon.

On the serializing side, a record's accessors can be used to extract the values of its components . On the deserializing side, the only way to instantiate the record object is to invoke the record's canonical constructor, which is passed the appropriate component values.

It is worth noting that starting in Java 15, core reflection will no longer be able to mutate the component fields of a record object. Construction should proceed through the canonical constructor.

Again, I'd love to to help to make XStream work out-of-the-box with records, so let me know if there is anything I can contribute.

Hi,

yes, any contribution is welcome. Personally I have not yet looked at Records at all, but if you can provide a converter, that's fine.

Regards,
Jörg
