Setter of the property is a set method declared alongside the property.

interface Setter<R> : Accessor<R>, KFunction<Unit>

The setter of this mutable property, used to change the value of the property.

abstract val setter: Setter<R>

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?

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?

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

var KCallable<*>.isAccessible: Boolean

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?

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?

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?

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

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

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

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

Returns an annotation of the given type on this element.

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

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

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

Returns true if this element is annotated with an annotation of type T.

fun <T : Annotation> KAnnotatedElement.hasAnnotation(): Boolean

Represents a var-property without any kind of receiver.

interface KMutableProperty0<R> : 
    KProperty0<R>, 
    KMutableProperty<R>

Represents a var-property, operations on which take one receiver as a parameter.

interface KMutableProperty1<T, R> : 
    KProperty1<T, R>, 
    KMutableProperty<R>

Represents a var-property, operations on which take two receivers as parameters.

interface KMutableProperty2<D, E, R> : 
    KProperty2<D, E, R>, 
    KMutableProperty<R>

interface KMutableProperty2<T1, T2, R> : 
    KProperty2<T1, T2, R>, 
    KMutableProperty<R>
