Referencing parent values during custom (de)serialization

[Ben Foster]

Is there currently any way to reference parent objects' property values from within a custom serializer/deserializer?  

For example, given the following structure:

class Parent {

  @SomeAnno1

  String id;

  @SomeAnno2

  Date createDate;

  OtherClass child;

}

class OtherClass {

  @AnnotationToTriggerCustomSerializer

  String value;

}

What I need, is during serialization and deserialization of OtherClass.value, to get the values of parent fields with the @SomeAnno1 and @SomeAnno2 (in this case id and createDate) in order to properly serialize the value.  I do not want to have a custom serializer assigned to Parent.id and Parent.createDate because those fields may already have serializers that I don't want to affect.

I've seen notes about using the new contextual attributes, but haven't been able to get this to actually work for me.  Is this possible?

Thanks!

There is no direct support for this at this point. It would now be possible to add a feature to start passing this information via contextual attributes, but such feature has not yet been implemented. This requires some care just make sure that cost is trivial for case where information is not needed.
