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

问题

Is there a way to identify a Kotlin data class from a regular Kotlin class? Like using reflection maybe?

回答1:

Since 1.1 there is an isData property on the class

MyDataClass::class.isData

回答2:

You can't read data annotation by reflection because it has default retention(CLASS).

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

But note that somethings of this are implementation details and may be changed in the future.
