Is the toString method of data classes deterministric? Or the order of fields isn't guaranteed?

[Iaroslav Postovalov]

It is.

[Iaroslav Postovalov]

The toString method is generated statically during compilation, and the order of fields is equal to their order in the class's definition.

[Iaroslav Postovalov]

e.g.: data class Unary(val operation: String, val value: MST) : MST() ->

public String toString() {
   return "Unary(operation=" + this.operation + ", value=" + this.value + ")";
}

Cool, thanks!
