KProperty0

expect interface KProperty0<out V> : KProperty<V> , Function0<V>

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.

actual interface KProperty0<out V> : KProperty<V> , Function0<V>

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.

actual interface KProperty0<out V> : KProperty<V> , Function0<V>

Types

Getter

interface Getter<out V> : KProperty.Getter<V> , Function0<V>

Getter of the property is a get method declared alongside the property.

Functions

call

abstract fun call(vararg args: Any?): V

Calls this callable with the specified list of arguments and returns the result. Throws an exception if the number of specified arguments is not equal to the size of parameters, or if their types do not match the types of the parameters.

callBy

abstract fun callBy(args: Map<KParameter, Any?>): V

Calls this callable with the specified mapping of parameters to arguments and returns the result. If a parameter is not found in the mapping and is not optional (as per KParameter.isOptional), or its type does not match the type of the provided value, an exception is thrown.

get

expect abstract fun get(): V

Returns the current value of the property.

actual abstract fun get(): V

Returns the current value of the property.

actual abstract fun get(): V

Returns the current value of the property.

actual abstract fun get(): V

getDelegate

abstract fun getDelegate(): 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.

Since Kotlin

1.1

invoke

abstract operator fun invoke(): V

Properties

annotations

abstract val annotations: List<Annotation>

Annotations which are present on this element.

getter

abstract override val getter: KProperty0.Getter<V>

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

isAbstract

abstract val isAbstract: Boolean

true if this callable is abstract.

isConst

abstract val isConst: Boolean

true if this property is const. See the Kotlin language documentation for more information.

isFinal

abstract val isFinal: Boolean

true if this callable is final.

isLateinit

abstract val isLateinit: Boolean

true if this property is lateinit. See the Kotlin language documentation for more information.

isOpen

abstract val isOpen: Boolean

true if this callable is open.

isSuspend

abstract val isSuspend: Boolean

true if this is a suspending function.

name

expect abstract val name: String

actual abstract val name: String

The name of this callable as it was declared in the source code. If the callable has no name, a special invented name is created. Nameless callables include:

actual abstract val name: String

The name of this callable as it was declared in the source code. If the callable has no name, a special invented name is created. Nameless callables include:

actual abstract val name: String

The name of this callable as it was declared in the source code. If the callable has no name, a special invented name is created. Nameless callables include:

parameters

abstract val parameters: List<KParameter>

Parameters required to make a call to this callable. If this callable requires a this instance or an extension receiver parameter, they come first in the list in that order.

returnType

abstract val returnType: KType

The type of values returned by this callable.

returnType

abstract val returnType: KType

The type of values returned by this callable.

typeParameters

abstract val typeParameters: List<KTypeParameter>

The list of type parameters of this callable.

visibility

abstract val visibility: KVisibility?

Visibility of this callable, or null if its visibility cannot be represented in Kotlin.

Inheritors

KMutableProperty0

Extensions

getValue

inline operator fun <V> KProperty0<V>.getValue(thisRef: Any?, property: KProperty<*>): V

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.

isInitialized

val KProperty0<*>.isInitialized: Boolean

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