Setter

interface Setter<D, E, R> : Setter<R>, (D, E, R) -> Unit

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

setter

abstract val setter: Setter<D, E, R>

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

getter

abstract val getter: Getter<D, E, R>

The getter of this property, used to obtain the value of the property.

set

abstract fun set(receiver1: D, receiver2: E, value: R)

Modifies the value of the property.

get

abstract fun get(receiver1: D, receiver2: E): R

Returns the current value of the property. In case of the extension property in a class, the instance of the class should be passed first and the instance of the extension receiver second.

getDelegate

abstract fun getDelegate(receiver1: D, receiver2: E): Any?

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.

extensionReceiverParameter

val KCallable<*>.extensionReceiverParameter: KParameter?

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

instanceParameter

val KCallable<*>.instanceParameter: 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.

isAccessible

var KCallable<*>.isAccessible: Boolean

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

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.

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.

valueParameters

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

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

findAnnotation

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

Returns an annotation of the given type on this element.

findParameterByName

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

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

getExtensionDelegate

fun <D> KProperty2<D, *, *>.getExtensionDelegate(
    receiver: D
): Any?

Returns the instance of a delegated member extension property, or null if this property is not delegated. Throws an exception if this is not an extension property.
