Kotlin reflection - getting all class field names

Question

How can I get a list of the Kotlin it data class declaredFields? How javagetDeclaredFields()

And if possible, is it also possible to filter publicand fields private? (Like Java Modifier.isPrivate(field.getModifiers()))

Answer 1

You probably want to get class properties, not fields. This can be done as follows:

MyClass::class.declaredMemberProperties

Getting fields is also possible through Java reflection:

MyClass::class.java.declaredFields

But fields are more likely an implementation in Kotlin, because some properties cannot have fields.

As for visibility, for properties you can check getter visibility modifiers:

val p = MyClass::class.declaredMemberProperties.first()
val modifiers = p.javaGetter?.modifiers

: null private val @JvmField. p.javaField.

, modifiers null, Modifier.isPrivate(...).

Kotlin getter setter, , , .
