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

Came up with a more generic solution

inline fun > findEnumConstantFromProperty(predicate: (T) -> Boolean): T? =
T::class.java.enumConstants?.find(predicate)

Example usage:

findEnumConstantFromProperty { it.value == 1 } // Equals Type.A
