how are enum classes implemented on the JVM? do they produce code that’s similar to a java enum ? asking because i’m trying to figure out how swagger annotations work and if i can rename them

[Rob Elliot]

I’m 99% sure they are the same as Java enums when compiled.

If you’re using IntelliJ you can view Kotlin bytecode and the decompile it to Java to check it out.

how do i view the bytecode / decompile to java? i’m using bazel and not sure if it makes any difference

[Zach Klippenstein (he/him) [MOD]]

Yes, kotlin enums are the same thing as java enums.

If you’re using IntelliJ, hit ctrl+shift+a and type “show kotlin bytecode”

[Pratik Tandel]

on a related note, is it possible to override the string rep (bidirectional) for an enum?

[Pratik Tandel]

i can’t write my enum like SOLE-PROP because - is invalid but in my API that’s being autogenerated i want it to have a hyphen

[Zach Klippenstein (he/him) [MOD]]

enums can have constructor params and properties, and you can store whatever data you like and implement toString yourself.

If you’re serializing/deserializing, you’ll have to consult the documentation for the library you’re using to determine how to override names
