Extensions

Link copied to clipboard
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.call. Otherwise, calls the suspend function with current continuation.

Since Kotlin 1.3
Link copied to clipboard
suspend fun <R> KCallable<R>.callSuspendBy(args: Map<KParameter, 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.

Since Kotlin 1.3
Link copied to clipboard

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

Since Kotlin 1.1
Link copied to clipboard

Returns an annotation of the given type on this element.

Since Kotlin 1.1
Link copied to clipboard

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

Since Kotlin 1.1
