cast<R> method

@override ValueStream<R> cast<R>()

Adapt this stream to be a Stream<R>.

This stream is wrapped as a Stream<R> which checks at run-time that each data event emitted by this stream is also an instance of R.

Implementation

@override
ValueStream<R> cast<R>() {
  return ValueStream(
    stream.cast<R>(),
    _lastVal as R Function(),
  );
}
