Hi guys. Is there an easy way to exclude a property from being used in generated toString() in data class (without implementing my own toString())?

[mfulton26]

gerson: data class Person(val name: String, parent: Person) { val parent: Person = parent }

[robin]

That doesn't work, data classes are not allowed to have non-val and non-var parameters

[mfulton26]

oh yeah; I forgot; I suppose data class Person(val name: String) { var parent: Person }

[mfulton26]

and then you could add a secondary constructor if you wanted to pass parent in.

[mfulton26]

And if you want parent to be a val then you would need to create a private var backing a public val.

That should work, but that's getting quite complicated already... I think overwriting toString might be the easiest way.

[mfulton26]

Yes, it may be. Or just include the property.

@robin You're right, that's getting quite complicated. I think I'll go with writing my own toString.

@mfulton26 Thanks for the suggestion, anyway!
