enumValueOf

this method require type parameter, but I have no it...

[kevinmost]

ah yeah, if you don't know the type at compile-time, that won't work. Why can't you use java.lang.Enum.valueOf?

[xkor]

because it also require type parameter(

[xkor]

and it is not compiling java.lang.Enum.valueOf<Enum<*>>(type.java, value)

[kevinmost]

it's not ideal, but you could define an unsafe Java util method that uses a raw type:

@SuppressWarnings("unchecked")
    @Nullable 
    public static Enum<?> enumValueOf(@NonNull Class<Enum> type, @NonNull String name) {
        return Enum.valueOf(type, name);
    }

[kevinmost]

the problem seems to me to be the enum's self-referencing generic type

[kevinmost]

that method returns @NonNull actually 🙂

[xkor]

I found solution!
type.java.enumConstants.first { it.toString() == value }

[kevinmost]

nice, that seems like a cleaner solution

[kevinmost]

maybe check it.name == value, since that's what Enum.valueOf and enumValueOf check

[xkor]

in common yes. But in my case toString is better, because I use toString to serialise
