示例1: filter
import akka.stream.Graph; //導入依賴的package包/類
/**
* Creates a flow that feeds each event into [selector], and:
* - If the selector emits a result, that result, and further results that also match, are fed through [target], and then merged into the stream.
* - If the selector emits {@link ReadProtocol#none()}, the event is passed downstream unchanged
* - If the selector emits a failure, the stream is failed.
*/

.splitWhen(Marker.class::isInstance)

.flatMapConcat(t -> {
// This is safe because all of the "tail" in "prefixAndTail" above comes from the original stream of E.
Source<E, NotUsed> source = uncheckedCast(t.second());
