How to select correct enum value from a kotlin function

Issue

i am expecting some string value and i need to find, if i have corresponding enum value defined.

my enum value is

enum class Status {
    Created, Updated
}

and what i want to achieve in this function is to check if any of these enum values matching, ignore the case

private fun getStatus(
        value: String
    ): Status {
        ....
    }

if nothing matched then i want to throw an error.

thank you so much for your help in advance!!

Solution

The built-in functions for enums like Enum.valueOf or enumValueOf<Enum> are case-sensitive, but you can easily write your own case-insensitive versions:

inline fun <reified T : Enum<T>> enumValueOfIgnoreCase(key: String): T =
    enumValues<T>().find { it.name.equals(key, ignoreCase = true) }
        ?: throw IllegalArgumentException("no value for key $key")

Then you can write for instance the following to obtain the Status element Created:

val status = enumValueOfIgnoreCase<Status>("created")
