Functions

dispatchEvent

open fun dispatchEvent(event: Event): Boolean

postMessage

fun postMessage(message: ERROR CLASS: Symbol not found for JsAny??, transfer: ReadonlyArray<Transferable>)

The postMessage() method of the Worker interface sends a message to the worker. The first parameter is the data to send to the worker. The data may be any JavaScript object that can be handled by the structured clone algorithm.

fun postMessage(message: ERROR CLASS: Symbol not found for JsAny??, options: StructuredSerializeOptions = definedExternally)

fun postMessage(message: String, transfer: ReadonlyArray<Transferable>)

fun postMessage(message: String, options: StructuredSerializeOptions = definedExternally)

terminate

fun terminate()

The terminate() method of the Worker interface immediately terminates the Worker. This does not offer the worker an opportunity to finish its operations; it is stopped at once.

when

fun <T : Event> when(type: EventType<T>, options: ObservableEventListenerOptions?): Observable<T>
