I've got a sealed class which overrides toString(), and has data class subclasses

in the subclasses, I have functions which have format strings with $this in them. surprisingly, the toString() implementation used is the default, non-override Kotlin implementation
if I add override fun toString() = super.toString() to each subclass, I get the expected toString() implementation, but IntelliJ marks it as a redundant overriding method
is IntelliJ just wrong, or is there a better way to do this?

wait, is this a limitation of format strings?

If IntelliJ is marking a toString override in a data class as redundant, then yes, IntelliJ is wrong. It doesn’t do that for me, though. It warns me about the redundant override in a normal class, but if I make it a data class the warning goes away.

A data class automatically overrides toString, which is why you’re seeing the “default” implementation being used. Providing your own override is basically a way to replace the default override.

I see. thank you 👍

(and yes, IntelliJ does warn about it being redundant in my case)

IIRC you need to mark it as final to change that behaviour somehow
