Add Helper Functions

In this task, you will add two helper functions to query a subscriber and purchase an offer.

Procedure

  1. Edit the DemoServices.java file.
  2. Add the subscriber query helper function. 
    private SubscriberResponse query(String route, RestQueryTerm term, SubscriberQuery req)
    throws Exception
{
    SubscriberResponse rsp = new SubscriberResponse();
    JsonObject json = new JsonObject();
 	
    service_subscriber_query(route, json, term, req, rsp);
    return rsp;
}

    This function performs a subscriber query using the extended subscriber query operation service_subscriber_query which is part of the JsonStubs class. This method performs a standard SubMan query and then extends the returned data using pricing cache information.

  3. Add the offer purchase helper function. 
    private MtxResponsePurchase purchase(
    String route,
    MtxSubscriberSearchData searchData,
    MtxPurchasedOfferData offer)
{
    MtxRequestSubscriberPurchaseOffer purchaseRequest
        = new MtxRequestSubscriberPurchaseOffer();
    MtxResponsePurchase response = null;
    purchaseRequest.setSubscriberSearchData(searchData);
    purchaseRequest.appendOfferRequestArray(offer);
    response = m_api.subscriberPurchaseOffer(route, purchaseRequest);
    return response;
}

    This helper function performs an offer purchase. Note that the response uses m_api which is an instance of the code-generated SubMan API and is managed by the JsonStubs class.

  4. Save the file.
