Let's say I have:
inline class Email(value: String)
fun something(email: Email)
now if I want to call
something() from Java I can't. Because any method that is accepting an inline class as a parameter is "mangled" (more about this here: https://kotlinlang.org/docs/reference/inline-classes.html#mangling) As far as I understood mangling renames the method name to include a "-" that's an invalid character in Java, so the method is practically invisible from Java perspective. That's intentional probably because of strong type safety. But I really need to make the method callable from both Java and Kotlin. Do you know some workaround?
According to the KEEP that is used to discuss and plan inline classes, this is not currently possible (writing as of 1.3.11):
We'll compile function
<hash>is a mangling suffix for the signature. Now it will not possible to call this function from Java because - is an illegal symbol there, but from Kotlin point of view it's a usual function with the name compute. [Emphasis mine]
Keep in mind that inline classes are experimental and subject to change, so perhaps in a future release this will be possible. I did try annotating this with @JvmName and that is also not supported.
