KTypes
KTypes is a zero-dependency Kotlin library for accurately introspecting type information
Examples
import kotlin.reflect.full.createType
interface Bar<T> : List<Array<T?>>
interface Foo : Bar<String>
fun main() {
val fooType = Foo::class.createType()
val collectionElementType = fooType.collectionElementType
println(collectionElementType)// Array<String?>
}
import kotlin.reflect.full.createType
interface Bar<T1, T2> : Map<T1, List<T2>?>
interface Foo : Bar<String, Int?>
fun main() {
val fooType = Foo::class.createType()
val mapType = fooType.findSuperType(Map::class)
val mapKeyType = fooType.mapKeyType
val mapValueType = fooType.mapValueType
println(mapType)// Map<String, List<Int?>?>
println(mapKeyType)// String
println(mapValueType)// List<Int?>?
}
import kotlin.reflect.full.createType
interface Bar<T> : List<Array<T?>>
interface Foo : Bar<String>
fun main() {
val fooType = Foo::class.createType()
println(fooType.isFinal)// false
println(fooType.isOpen)// false
println(fooType.isAbstract)// true
println(fooType.isSealed)// false
println(fooType.isData)// false
