KProperty0

expect interface KProperty0<out V> : KProperty<V> , Function0<V> (source)

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.

Functions

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.

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.

@ExperimentalReflectionOnLambdas
fun <R> Function<R>.reflect(): KFunction<R>?

This is an experimental API. Given a class for a compiled Kotlin lambda or a function expression, returns a KFunction instance providing introspection capabilities for that lambda or function expression and its parameters. Not all features are currently supported, in particular KCallable.call and KCallable.callBy will fail at the moment.

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