propertyValue can be null here

That’s actually intentional here, since this change allows propertyValue to be null if the converter has indicated it can handle null values.

Then you should change the signature of ToJson to allow nulls

@AndriySvyryd That's a good point! I had some reservations about that but didn't really give it much thought. I've looked at it more now and FWIG JsonValueReaderWriter currently doesn't allow null input by design, and I'm not sure changing that would make sense and/or would require a different setup all together.

If I change JsonValueReaderWriter to allow null argument for object value, I can't just pass it to ToJsonTyped. I would have to make ToJsonTyped value argument nullable aswell, but I don't think that would be desired. AFAIK The typed JsonValueReaderWriter<T> should generally not have to worry about null values. I've considered having JsonConvertedValueReaderWriter inherit from non-typed JsonValueReaderWriter to solve this. Then I could add a null check and write in the JsonValueReaderWriter<T>.ToJson implementation and also the JsonConvertedValueReaderWriter.ToJson implementation. However, materialization works with the typed JsonValueReaderWriter<T>.FromJsonTyped, so the JsonConvertedValueReaderWriter wouldn't be usable in materialization. I think that if we want to make ToJson accept null and do the null write for the value, the only option that makes sense would be unsealing JsonValueReaderWriter<T>.ToJson so that I can override it in JsonConvertedValueReaderWriter. However, I'm not sure that is desirable either.

Some workarounds could be:

  • Adding a method to IJsonConvertedValueReaderWriter that allows null input, then doing the ConvertsNulls check and null write there
  • Leveraging IJsonConvertedValueReaderWriter.ValueConverter and ICompositeJsonValueReaderWriter.InnerReaderWriter to circumvent JsonConvertedValueReaderWriter.ToJson. Invoking the ValueConverter manually and checking if it converted to null (seems cumbersome)
  • Accepting the null suppression for this specific instance

I think this exposed the reason I find this suppression smelly: it's relying on implementation details. You could add JsonValueReaderWriter.HandlesNulls, make the value nullable and throw if it's null and HandlesNulls is false

I'm wondering now how this should (not) affect FromJson

I think we can have FromJson stay unaffected, but would recommend renaming to HandlesNullWrites
Otherwhise a similar signature change for FromJson would be needed, but materialization uses FromJsonTyped
