How to iterate through MeasurementCollection

[vaibhavi_ghumare]

MeasurementFilter measurementFilter = new MeasurementFilter();
measurementFilter.bySource(new GId(“12345679”));
measurementFilter.byDate(startDate.toDate(), endDate.toDate());
measurementFilter.byFragmentType(“IsProgramRunning”);

   MeasurementCollection measurementCollection = measurementApi.getMeasurementsByFilter(measurementFilter);

I am getting measurements in measurementCollection type, How to display all the measurements in that collection in java

[Michael_Voigt2]

You can use a simple .get() on the collection and then loop over it as described in the doc:
https://cumulocity.com/guides/microservice-sdk/java/#accessing-events-and-measurements

[vaibhavi_ghumare]

MeasurementFilter measurementFilter = new MeasurementFilter();
measurementFilter.bySource(new GId(“1234567”));
measurementFilter.byDate(startDate.toDate(), endDate.toDate());

    System.out.println("measurementCollection Filter");
    MeasurementCollection mc = measurementApi.getMeasurementsByFilter(measurementFilter);

    MeasurementCollectionRepresentation mcr;
    
    for (mcr = mc.get(); mcr != null; mcr = mc.getNextPage(mcr)) {
        for (MeasurementRepresentation mp : mcr.getMeasurements()) {
            System.out.println(mp);
        }
        System.out.println("2nd loop");
    }

Going in infinite loop

[Stefan_Witschel]

Why not using an iterator?

measurementApi.getMeasurementsByFilter(measurementFilter).get().allPages().forEach(measurement -> {
    System.out.println(measurement);
});

I assume Vaibhavi was following the code example from the doc: Microservice SDK for Java - Cumulocity IoT Guides - even if the code is not as nice as your example, I dont know why that would result in an infinite loop…

[Harald_Meyer]

Which loop goes into the inifinite loop? I assume the outer one? Does it print “2nd loop” continously?

[vaibhavi_ghumare]

Yes, Outer Loop, Its printing 2nd loop continuously.
