Is it possible to implement an expect class in JVM with a property path and the extending class has a method getPath() ? (I'm talking about File class).

I'm trying something like actual class MyFile extends <http://java.io|java.io>.File and MyFile has a property path.

i think that works if it’s a typealias instead of an extends

[edenman]

actual typealias MyFile = <http://java.io|java.io>.File

[jdiaz]

That would work if the methods weren't a little bit different and I wasn't able to create actual extension methods to that typealias

[edenman]

best i could come up with:

actual class MyFile(pathname: String) : File(pathname) {
  actual val myPath: String
    get() = path
}

[edenman]

couldn’t get around the “accidental override” if the name is the same

[jdiaz]

That's what I came up with, and one can't override getPath as it's final, I wouldn't like to call it mypath as it works everywhere and I wouldn't like to have a backing object as that means 2 objects every time it is instantiated but it seems is what I'll have to do

I would be fine if I found a synonym for path, lol
