Allow `@JsonAnySetter` on Creators #4558

JooHyukKim · 2024-06-01T13:00:39Z

resolves #562

This version is more adherent to existing call flow and simply extends existing implementations, such as....

Introduction of SettableAnyProperty subclasses JsonNodeParameterAnyProperty and MapParameterAnyProperty
Introduction of SettableAnyProperty methods getParameterIndex() createParameterObject() to streamline deserialization by PropertyValueBuffer

Also suggestions from PR #4366 have been followed

Added support for JsonNode and ObjectNode
Added tests for record also

…rops()

…r can just pour into the any-setter

Excellent progress! Hoping to review this in detail (had a quick look, much improved from what I already saw -- and not just wrt addressing things I mentioned but overall)

FWTW, this is part of one of two listed "major design/implementation issues" page:

https://github.com/FasterXML/jackson-future-ideas/wiki/Major-Design---Implementation-Issues

so not "just" one of top-voted Mostly Wanted features but also considered a significant design/implementation concern.

src/main/java/com/fasterxml/jackson/databind/deser/BasicDeserializerFactory.java

-            if (name == null) {
+            boolean isAnySetter = Boolean.TRUE.equals(ctxt.getAnnotationIntrospector().hasAnySetter(param));
+            if (isAnySetter) {
+                if (anySetterFound) {


Looks like we lose information on any-setter, and only call introspector to find multiples here... but then need to re-introspect later on?

I remembered now, this code serves two purposes.

One is to detect and handle multiple any-setter (which, as you said, could be moved to later one below)

The other one, which I do need help with is... not any-setter not having any property name here. So any-setter creator parameter without any name specified (via @JsonProperty) throws error.

LMK if you have better idea with the second problem I am facing, @cowtowncoder

Ah. Yes. For that purpose, we could only do a lookup if name not found. Let me think about this a bit, good point, something is needed here.

Phew, that was alot of work 😆 Hopefully, it won't be too hard merging into master.
Thank you for your help! @cowtowncoder

cowtowncoder · 2024-06-09T03:30:43Z

@JooHyukKim thank you for actually implementing it & going through all tiny things I wanted changed :)

Surprisingly merge to master was quite straight-forward this time around.

And with this, we are getting somewhat close to 2.18.0 minimum feature set, as far as I care.
I do want this performance optimization: FasterXML/jackson-core#1284 for streaming but otherwise not many must-haves.
