Is there a better (or "more Kotlin") way to get an enum value when I don't have a concrete type? It feels weird having to resort to java.lang.Enum...

sealed class EnumBinding<E : Enum<E>>(
	private val enumType: Class<E>
) : Binding<Any?, E?> {

	override fun converter(): Converter<Any?, E?> = object : Converter<Any?, E?> {
		override fun from(databaseObject: Any?): E? =
			databaseObject?.let { java.lang.Enum.valueOf(enumType, it.toString()) }
        …
    }
    …
}

(it's a custom jOOQ binding, so I can't change Binding or Converter)

tl;dr ideally there would be, and there's a feature request, but for now there's no way to it without Java reflection

Thank you! Upvoted. (but 5 years already … 😟)

Doesn’t this function work here? https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/enum-value-of.html

no, because you can't write a concrete type for T

I see, thanks
