Example 1 with AllWindowFunction

use of org.apache.flink.streaming.api.functions.windowing.AllWindowFunction in project flink by apache.

the class StateDescriptorPassingTest method testApplyWindowAllState.

@Test
public void testApplyWindowAllState() {
    final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
    env.registerTypeWithKryoSerializer(File.class, JavaSerializer.class);
    // simulate ingestion time
    DataStream<File> src = env.fromElements(new File("/")).assignTimestampsAndWatermarks(WatermarkStrategy.<File>forMonotonousTimestamps().withTimestampAssigner((file, ts) -> System.currentTimeMillis()));
    SingleOutputStreamOperator<?> result = src.windowAll(TumblingEventTimeWindows.of(Time.milliseconds(1000))).apply(new AllWindowFunction<File, String, TimeWindow>() {

        @Override
        public void apply(TimeWindow window, Iterable<File> input, Collector<String> out) {
        }
    });
    validateListStateDescriptorConfigured(result);
}
