Esper (CEP)의 win_ext 창에 대한 이해에 도움이 필요합니다. 나이 (처음 2) 이벤트가 여전히이 된 경우에도 업데이트-방법에 팝업 이유가 궁금하네요 "만료"esper_ext timed가 이전 항목을 필터링하지 않는 이유
public class MyCepTest {
public static void main(String...args) throws Exception{
System.out.println("starting");
MyCepTest ceptest = new MyCepTest();
ceptest.execute();
System.out.println("end");
}
public void execute() throws Exception{
Configuration config = new Configuration();
config.addEventType(MyPojo.class);
EPServiceProvider epService = EPServiceProviderManager.getDefaultProvider(config);
EPAdministrator admin = epService.getEPAdministrator();
EPStatement x1 = admin.createEPL(win);
EPStatement x2 = admin.createEPL(win2);
x1.setSubscriber(this);
x2.setSubscriber(this);
EPRuntime runtime = epService.getEPRuntime();
ArrayList<MyPojo> staffToSendToCep = new ArrayList<MyPojo>();
staffToSendToCep.add(new MyPojo(1, new Date(1490615719497L)));

}
Thread.sleep(500);
System.out.println("round 2...");//why two first Pojos are still found? Shouldn't ext_timed(pojoTime.time, 300 seconds) rule them out?
staffToSendToCep.add(new MyPojo(3, new Date(1490616949497L)));
for(MyPojo pojo : staffToSendToCep){

}
}

System.out.println(map);
}
public static String win = "create window fiveMinuteStuff.win:ext_timed(pojoTime.time, 300 seconds)(pojoId int, pojoTime java.util.Date)";
public static String win2 = "insert into fiveMinuteStuff select pojoId,pojoTime from MyPojo";
}
class MyPojo{
int pojoId;
Date pojoTime;
MyPojo(int pojoId, Date date){
this.pojoId = pojoId;
this.pojoTime = date;
}
public int getPojoId(){
return pojoId;
}
public Date getPojoTime(){

public String toString(){

}
나는 잠시 동안이와 당황 봤는데 도움이 될 것이라고 크게
감사
