Notifies the observer that the provider has finished sending push-based notifications.

Examples

The following example provides an implementation of the OnCompleted method in a latitude/longitude tracking application. The method simply reports that no further data is available and calls the provider's IDisposable.Dispose implementation. See the Example section of the IObserver<T> topic for the complete example.

void on_completed() noexcept override {
  console::write_line("The location Tracker has completed transmitting data to {}.", name());
  unsubscribe();
}
