Is there a way to identify a Kotlin data class from a regular Kotlin class?

Question

Is there a way to identify a Kotlin data class from a regular Kotlin class? How, for example, the use of reflection?

Answer 1

Starting with 1.1, the isData property exists in the class

MyDataClass::class.isData 

Answer 2

You cannot read data annotation with reflection because it has a default hold ( CLASS ).

You can try to use some heuristics, for example, check that it contains the following methods:

• public final copy
• public final component{N}
• public static copy$default

But note that some of them are implementation details and are subject to change in the future.
