I have a simple problem where I’m not sure how to solve it in the most type save way. I have two sets of well known values, which means that enums seem like a natural fit. However, those enums are parameterized with description texts. How do I write a generic function that takes the whole enum as a parameter? Enums can’t inherit from a “parameterized enum”. Can they implement interfaces? Can I even reference the whole enum set, or do I have to pass the SomeEnum.values() array around?

Enums are fully fledged objects so yes, they can implement interfaces. To access the enum values you can either pass around the values array, use

MyClass::class.java.enumConstants

or use

EnumSet.allOf(MyClass::class.java)

.

Okay thanks, I’ll see if I can make them implement a getText interface and pass around the values array, since that looks more intuitive to me than the other options.
