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? Like using reflection maybe?

Answer 1

Since 1.1 there is an isData property on the class

MyDataClass::class.isData

Answer 2

Since Kotlin 1.1 use isData property on KClass. (docs)

Before Kotlin 1.1 you can try to use some heuristics, like check that it contains next methods:

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

Note these implementation details could be changed in the future.
