Hi guys. Is there a simple way to do cyclic data classes? If I do it normaly most of the methods will break.

Would you mind expanding on what you mean by “cyclic”?

[Zemeio]

data class Parent(child: Child); data class Child(parent: Parent)

Something like this.

Why would you want it to be a data-class? What for?

[Zemeio]

They are classes I use on services, and might want to save on database. I researched a bit, and found I can just define the parent reference outside of the propeties. However, I think I would have to make it nullable, which I`m not sure I want.

[Zemeio]

Like data class Parent(child: Child); data class Child(){var parent: Parent?} or something.

That doesn't tell why you want the data modifier, does it?

[Zemeio]

Aren`t data classes used for seralizing?

[elizarov]

Usually “serailizable” classes are serailized. Data classes are used for simple data containers.
