[nick-ikea]

Here is the result of generated enum keys:

enum class WeightUomCodeType(val value: String) {
Grm("GRM"),
Kgm("KGM"),
Lbr("LBR"),
Stn("STN"),
Tne("TNE");

companion object {
    fun fromValue(value: String): WeightUomCodeType = when (value) {
        "GRM" -> Grm
        "KGM" -> Kgm
        "LBR" -> Lbr
        "STN" -> Stn
        "TNE" -> Tne
        else  -> throw IllegalArgumentException()
    }
}

}
