How to generate custom OpenAPI response for double array parameters?

How to generate custom OpenAPI response for double array parameters?

If this is my Java code:

@JSONVIEW(Views.Abridged.class)
@Schema(type = SchemaType.ARRAY,
description = "Multi-dimensional Array.",
example = "[[[1.23, 1.0903]]]")
private List<Double[][]> data;

This is the current smallrye openapi:

"data": {
"description": "Multi-dimensional Array.",
"type": "array",
"items": {},
"example": [
[
[
1.23,
1.0903
]
]
]
},

I need it to be more like this:

"data": {
"type": "array",
"description": "Multi-dimensional Array.",
"example": [
[
[
1.23,
1.0903
]
]
],
"items": {
"type": "array",
"items": {
"type": "array",
"items": {
"type": "number",
"format": "double"
}
}
}

How can I achieve this?

From what I can tell the OASFilter does not get triggered/called for object properties. Is that wrong and it does get called? Or is there a different way to customize how double arrays are handled?

@dhoffer I'm a little surprised it didn't work just as you have it, but you should be able to set implementation = Double[][][].class in your @Schema to get the result you expect.

Yes that worked, thanks. I noted that arrays of any depth work fine w/o the implementation. The case where it doesn't work w/o implementation is where we have List<Double[][]>
