Topic: Java org.hl7.fhir.r4.model Help

Hi all. I'm using the java org.hl7.fhir.model classes. The profile I am working with redefines a property called criteria. The JSON file this includes a criteria and a _criteria property. Is there a way to get the _criteria property without using a generic Java JSON parser? Thanks!

That's just the way extra properties of primitive type element are represented in JSON. The standard library will load that fine.

the _criteria property is indicating the extension on criteria. you can read the extension directly with criteria.getExtension() from the org.hl7.fhir.model classes.

:+1: @Michele Mottini I did not know that here are other properties in addition to extensions ...

I believe it's restricted to fields from the Element type (id and extension). Details are on the JSON page.
