true if this callable is abstract.

abstract val isAbstract: Boolean

true if this callable is final.

abstract val isFinal: Boolean

true if this callable is open.

abstract val isOpen: Boolean

true if this is a suspending function.

abstract val isSuspend: Boolean

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:

abstract val name: String

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.

abstract val parameters: List<KParameter>

The type of values returned by this callable.

abstract val returnType: KType

The list of type parameters of this callable.

abstract val typeParameters: List<KTypeParameter>

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

abstract val visibility: KVisibility?

Annotations which are present on this element.

abstract val annotations: List<Annotation>

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.

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

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.

abstract fun callBy(args: Map<KParameter, Any?>): 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 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 function with introspection capabilities.

interface KFunction<out R> : KCallable<R>, Function<R>

Represents a property, such as a named val or var declaration. Instances of this class are obtainable by the :: operator.

interface KProperty<out V> : KCallable<V>
