KProperty0
interface KProperty0<out V> : KProperty<V>, () -> V(Common source) (JVM source) (JS source) (Native source)
Represents a property without any kind of receiver. Such property is either originally declared in a receiverless context such as a package, or has the receiver bound to it.
Types
Getter
Getter of the property is a get method declared alongside the property.
interface Getter<out V> : KProperty.Getter<V>, () -> VProperties
getter
The getter of this property, used to obtain the value of the property.
abstract val getter: KProperty0.Getter<V>Inherited Properties
getter
The getter of this property, used to obtain the value of the property.
abstract val getter: KProperty.Getter<V>isConst
true if this property is const.
See the Kotlin language documentation
for more information.
abstract val isConst: BooleanisLateinit
true if this property is lateinit.
See the Kotlin language documentation
for more information.
abstract val isLateinit: BooleanFunctions
get
Returns the current value of the property.
abstract fun get(): VgetDelegate
Returns the value of the delegate if this is a delegated property, or null if this property is not delegated.
See the Kotlin language documentation
for more information.
abstract fun getDelegate(): Any?invoke
abstract operator fun invoke(): VExtension Properties
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?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?isAccessible
Provides a way to suppress JVM access checks for a callable.
var KCallable<*>.isAccessible: BooleanisInitialized
Returns true if this lateinit property has been assigned a value, and false otherwise.
val KProperty0<*>.isInitialized: BooleanvalueParameters
Returns parameters of this callable, excluding the this instance and the extension receiver parameter.
val KCallable<*>.valueParameters: List<KParameter>Extension Functions
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?
): RcallSuspendBy
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?>
): RfindAnnotation
Returns an annotation of the given type on this element.
fun <T : Annotation> KAnnotatedElement.findAnnotation(): T?findAnnotations
Returns all annotations of the given type on this element, including individually applied annotations as well as repeated annotations.
fun <T : Annotation> KAnnotatedElement.findAnnotations(): List<T>fun <T : Annotation> KAnnotatedElement.findAnnotations(
klass: KClass<T>
): List<T>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?getValue
An extension operator that allows delegating a read-only property of type V to a property reference to a property of type V or its subtype.
operator fun <V> KProperty0<V>.getValue(
thisRef: Any?,
property: KProperty<*>
): VhasAnnotation
Returns true if this element is annotated with an annotation of type T.
fun <T : Annotation> KAnnotatedElement.hasAnnotation(): Booleanreflect
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.
