KMutableProperty1

interface KMutableProperty1<T, R> : 
    KProperty1<T, R>,
    KMutableProperty<R>
(source)

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

Types

Setter

interface Setter<T, R> : Setter<R>, (T, R) -> Unit

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

Properties

setter

abstract val setter: Setter<T, R>

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

Inherited Properties

getter

abstract val getter: Getter<T, R>

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

Functions

set

abstract fun set(receiver: T, value: R)

Modifies the value of the property.

Inherited Functions

get

abstract fun get(receiver: T): R

Returns the current value of the property.

getDelegate

abstract fun getDelegate(receiver: T): 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.

Extension Properties

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.

Extension Functions

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 KProperty1<*, *>.getExtensionDelegate(): Any?

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