Usage

From source file:demo.RxJavaTransformer.java

private static String processData(List<String> data) {

    if (data == null || data.size() == 0)
        return "";

    //start time to find out much time it takes to process data
    Long processingstarttime = System.currentTimeMillis();

    // filter the stream based on number of parameters. It should be 17
    List<String> filtereddata = filterData(data);

    // get the cell start and end information for each event and store it as EventData
    List<EventData> transformedData = transformData(filtereddata);

    // get list of all free taxies
    List<FreeTaxiData> freeTaxiesList = get50FreeTaxies(transformedData);

    // reduced transformed data based on "startendid" key which denotes the starting square and ending square
    List<EventDataCollection> eventsDataCollectionList = reducebyCount(transformedData);

    // Find top 10 areas where taxies are traveling the most
    List<RouteData> top10areas = getTop10Areas(eventsDataCollectionList);

    // Find data related to processing time
    List<String> processingInfoList = getProcessingInfo(processingstarttime, eventsDataCollectionList, data);

    totalEventsProcessed = totalEventsProcessed + data.size();

    // returned all required data as json
    ReturnedData obj = new ReturnedData(processingInfoList, freeTaxiesList, top10areas, totalEventsProcessed);
    ObjectMapper mapper = new ObjectMapper();
    String jsonInString = "";
    try {//w w w .  jav  a 2  s  . c o  m
        jsonInString = mapper.writeValueAsString(obj);
    } catch (Exception e) {
