Usage

From source file:io.pivotal.demo.smartgrid.frontend.timeseries.AggregateCounterTimeSeriesRepository.java

@Override
public Map<String, TimeSeriesCollection> getTimeSeriesData(TimeSeriesDataRequest dataRequest) {

    int houseId = dataRequest.getHouseId();

    IntStream houseNumStream = houseId == GRID_HOUSE_ID ? IntStream.rangeClosed(HOUSE_ID_MIN, HOUSE_ID_MAX)
            : IntStream.of(houseId);

    List<AggregateCounterCollection> aggregateCounterCollections = houseNumStream.parallel()
            .mapToObj(i -> new TimeSeriesDataRequest(dataRequest, i)).map(this::fetchAggregateCounterData)
            .filter(acc -> acc != null && !acc.getAggregateCounters().isEmpty()).collect(Collectors.toList());

    Map<String, TimeSeriesCollection> result = new HashMap<>();
    for (AggregateCounterCollection acc : aggregateCounterCollections) {

        TimeSeriesCollection tsc = convertToTimeSeriesCollection(acc);
        result.put(tsc.getName(), tsc);// w ww.  java2 s. c o  m
    }

    TimeSeriesCollection totalGridTimeSeriesCollection = aggreagteGridTotalTimeSeries(result);

    result.put("h_-1", totalGridTimeSeriesCollection);

    return result;
