kotlin reflection get list of fields

Question

is there an equivalent for the java reflection foo.getClass().getFields() in Kotlin? I could only find that I can access a field when I know it\'s name, but I would

Answer 1

Did you want fields as-in "backing field" or fields as in "properties" ... Kotlin really only has properties. You can get these for some class using:

MyTest::class.memberProperties

// or 

MyTest::class.declaredMemberProperties

And from a Java Class, use the kotlin extension property to get the Kotlin KClass from which you can proceed:

someClassOfMine.javaClass.kotlin.memberProperties

This requires the kotlin-reflect dependency as well to be added to your build and classpath. You'll find many other useful things on KClass

For the secret backing fields behind a property, use Java reflection at your own risk.
