Effective Enums in Kotlin with reverse lookup?

Question

I\'m trying to find the best way to do a \'reverse lookup\' on an enum in Kotlin. One of my takeaways from Effective Java was that you introduce a static map inside the enum

Answer 1

Another example implementation. This also sets the default value (here to OPEN) if no the input matches no enum option:

enum class Status(val status: Int) {
OPEN(1),
CLOSED(2);

companion object {
    @JvmStatic
    fun fromInt(status: Int): Status =
        values().find { value -> value.status == status } ?: OPEN
}

}
