Extension Properties

JVM
1.1

extensionReceiverParameter

Returns a parameter representing the extension receiver instance needed to call this callable, or null if this callable is not an extension.

val KCallable<*>.extensionReceiverParameter: KParameter?
JVM
1.1

instanceParameter

Returns a parameter representing the this instance needed to call this callable, or null if this callable is not a member of a class and thus doesn't take such parameter.

val KCallable<*>.instanceParameter: KParameter?
JVM
1.0

isAccessible

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

var KCallable<*>.isAccessible: Boolean

1.2

isInitialized

Returns true if this lateinit property has been assigned a value, and false otherwise.

val KProperty0<*>.isInitialized: Boolean
JVM
1.0

javaField

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

val KProperty<*>.javaField: Field?
JVM
1.0

javaGetter

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.

val KProperty<*>.javaGetter: Method?
JVM
1.0

javaSetter

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.

val KMutableProperty<*>.javaSetter: Method?
JVM
1.1

valueParameters

Returns parameters of this callable, excluding the this instance and the extension receiver parameter.

val KCallable<*>.valueParameters: List<KParameter>

Extension Functions

JVM
1.3

callSuspend

Calls a callable in the current suspend context. If the callable is not a suspend function, behaves as KCallable.call. Otherwise, calls the suspend function with current continuation.

suspend fun <R> KCallable<R>.callSuspend(
    vararg args: Any?
): R
JVM
1.3

callSuspendBy

Calls a callable in the current suspend context. If the callable is not a suspend function, behaves as KCallable.callBy. Otherwise, calls the suspend function with current continuation.

suspend fun <R> KCallable<R>.callSuspendBy(
    args: Map<KParameter, Any?>
): R
JVM
1.1

findAnnotation

Returns an annotation of the given type on this element.

fun <T : Annotation> KAnnotatedElement.findAnnotation(): T?
JVM
1.1

findParameterByName

Returns the parameter of this callable with the given name, or null if there's no such parameter.

fun KCallable<*>.findParameterByName(
    name: String
): KParameter?
JVM
1.0

reflect

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.

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