takeOrdered是否有一个flink等价物来过滤数据流中窗口中的前k个项目？

DataStream<Tuple2<String, Integer>> dataStream = ...; // 输入数据流

// 将数据流按照指定的窗口进行分组
WindowedStream<Tuple2<String, Integer>, String, TimeWindow> windowedStream = dataStream
    .keyBy(tuple -> tuple.f0)
    .timeWindow(Time.seconds(5));

// 对窗口中的数据按照指定的排序规则进行排序，并获取前3个项目
DataStream<Tuple2<String, Integer>> resultStream = windowedStream
    .apply((key, window, input, out) -> {
        List<Tuple2<String, Integer>> sortedList = input.takeOrdered(3, new TupleComparator());
        for (Tuple2<String, Integer> tuple : sortedList) {
            out.collect(tuple);
        }
    });

// 定义排序规则的比较器
public class TupleComparator implements Comparator<Tuple2<String, Integer>> {
    @Override
    public int compare(Tuple2<String, Integer> o1, Tuple2<String, Integer> o2) {
        return o1.f1.compareTo(o2.f1);
    }
}
