Package kotlin.reflect.jvm

Platform and version requirements: JVM

Runtime API for interoperability between Kotlin reflection and Java reflection provided by kotlin-reflect library.

Extensions for External Classes

java.lang.reflect.Constructor

java.lang.reflect.Field

java.lang.reflect.Method

Properties

isAccessible

var KCallable<*>.isAccessible: Boolean

Provides a way to suppress JVM access checks for a callable.

javaConstructor

val <T> KFunction<T>.javaConstructor: Constructor<T>?

Returns a Java Constructor instance corresponding to the given Kotlin function, or null if this function is not a constructor or cannot be represented by a Java Constructor.

javaField

val KProperty<*>.javaField: Field?

Returns a Java Field instance corresponding to the backing field of the given property, or null if the property has no backing field.

javaGetter

val KProperty<*>.javaGetter: Method?

Returns a Java Method instance corresponding to the getter of the given property, or null if the property has no getter, for example in case of a simple private val in a class.

javaMethod

val KFunction<*>.javaMethod: Method?

Returns a Java Method instance corresponding to the given Kotlin function, or null if this function is a constructor or cannot be represented by a Java Method.

javaSetter

val KMutableProperty<*>.javaSetter: Method?

Returns a Java Method instance corresponding to the setter of the given mutable property, or null if the property has no setter, for example in case of a simple private var in a class.

javaType

val KType.javaType: Type

Returns a Java Type instance corresponding to the given Kotlin type. Note that one Kotlin type may correspond to different JVM types depending on where it appears. For example, Unit corresponds to the JVM class Unit when it's the type of a parameter, or to void when it's the return type of a function.

jvmErasure

val KType.jvmErasure: KClass<*>

Returns the KClass instance representing the runtime class to which this type is erased to on JVM.

jvmName

val KClass<*>.jvmName: String

Returns the JVM name of the class represented by this KClass instance.

Functions

reflect

fun <R> Function<R>.reflect(): KFunction<R>?

This is an experimental API. Given a class for a compiled Kotlin lambda or a function expression, returns a KFunction instance providing introspection capabilities for that lambda or function expression and its parameters. Not all features are currently supported, in particular KCallable.call and KCallable.callBy will fail at the moment.
