override fun equals(other: Any?): Boolean = when(other) {
        this -> true

other

checked using == or === ?

if it doesn't return, it's ==

        val t1 = Test()
        val t2 = Test()

        Test().equals(Test()) shouldBe true
        (Test() === Test()) shouldBe false

        val maybe = when (t1) {
            t2 -> "yes"
            else -> "no"
        }

        println(maybe)
    }

yes

I cant test it yet, I'm in the middle of a port

isnt there a way to force structural equality then unless typing explicitely

other === this

==

05/24/2019, 12:18 PM

override fun equals(other: Any?): Boolean = when {
    other === this -> true
    // Check the type, then the equality of each properties
}

Also, why not using a

data class

equals

hashcode

are implemented automatically by the compiler.

it's a port from C#, I'd like to keep it as closest as possible,

data class

is out because of this

equals

is actually more complex than what I shown)

Do you want `equals`/`==

to be the same as

05/24/2019, 5:33 PM

no, I wanted to know if I could use somehow structural equality if I had

when(value)

Then you'll need to do what @tseisel says.
