loadProperty

See loadProperty_(Property, EntityValue, DataQuery?, HttpHeaders?, RequestOptions?).

Parameters

See loadProperty_(Property, EntityValue, DataQuery?, HttpHeaders?, RequestOptions?).

Parameters

See loadProperty_(Property, EntityValue, DataQuery?, HttpHeaders?, RequestOptions?).

Parameters

Load the value of a property into an existing entity. This can be applied to both structural and navigation properties.

Example using proxy classes:

open fun loadPropertyExample(): kotlin.Unit
{
    val service = this.service;
    val query = DataQuery()
        .select(Customer.customerID, Customer.companyName, Customer.contactName)
        .filter(Customer.customerID.equal("ALFKI")
            .or(Customer.customerID.equal("ANATR")));
    val responseHeaders = com.sap.cloud.mobile.kotlin.odata.http.HttpHeaders();
    val requestOptions = RequestOptions();
    requestOptions.captureResponseHeaders = responseHeaders;
    val customers = service.getCustomers(query, null, requestOptions);
    var countOrders = 0;
    L491@
    for (customer in customers)
    {
        this.showCustomer(customer);
        service.loadProperty(Customer.orders, customer);
        val orders = customer.orders;
        L496@
        for (order in orders)
        {
            val orderID = order.orderID;
            Example.show("  Order ", Example.formatInt(orderID));
            countOrders++;
        }
    }
    Assert.isTrue(countOrders > 0,
        "/Users/home/xmkbuilder/data/jenkins/prod-build7010/w/a1o59enhtx/src/main/xs/examples/example.NorthwindProxyClient.xs:503:9");
    Assert.isTrue(this.checkContentTypeJson(responseHeaders),
        "/Users/home/xmkbuilder/data/jenkins/prod-build7010/w/a1o59enhtx/src/main/xs/examples/example.NorthwindProxyClient.xs:504:9");
}

Example using proxy classes (in request batch):

open fun loadPropertyInBatchExample(): kotlin.Unit
{
    val service = this.service;
    val query = DataQuery()
        .select(Customer.customerID, Customer.companyName, Customer.contactName)
        .filter(Customer.customerID.equal("ALFKI")
            .or(Customer.customerID.equal("ANATR")));
    val customers = service.getCustomers(query);
    val customer1 = customers[0];
    val customer2 = customers[1];
    val query1 = DataQuery().load(customer1, Customer.orders);
    val query2 = DataQuery().load(customer2, Customer.orders);
    val secondResponseHeaders = com.sap.cloud.mobile.kotlin.odata.http.HttpHeaders();
    val secondRequestOptions = RequestOptions();
    secondRequestOptions.captureResponseHeaders = secondResponseHeaders;
    val batch = RequestBatch();
    batch.addQuery(query1);
    batch.addQuery(query2, null, secondRequestOptions);
    service.processBatch(batch);
    val result1 = batch.getQueryResult(query1);
    val result2 = batch.getQueryResult(query2);
    val orders1 = Order.list(result1.getEntityList());
    val orders2 = Order.list(result2.getEntityList());
    Assert.isTrue(orders1.size != 0,
        "/Users/home/xmkbuilder/data/jenkins/prod-build7010/w/a1o59enhtx/src/main/xs/examples/example.NorthwindProxyClient.xs:530:9");
    Assert.isTrue(orders2.size != 0,
        "/Users/home/xmkbuilder/data/jenkins/prod-build7010/w/a1o59enhtx/src/main/xs/examples/example.NorthwindProxyClient.xs:531:9");
    customer1.orders = orders1;
    customer2.orders = orders2;
    Assert.isTrue(this.checkContentTypeJson(secondResponseHeaders),
        "/Users/home/xmkbuilder/data/jenkins/prod-build7010/w/a1o59enhtx/src/main/xs/examples/example.NorthwindProxyClient.xs:534:9");
}

Example using dynamic API:

    val service = this.service;
    val customersEntitySet = service.getEntitySet("Customers");
    val customerEntityType = customersEntitySet.entityType;

    val ordersProperty = customerEntityType.getProperty("Orders");
    val orderIDProperty = ordersProperty.itemEntityType.getProperty("OrderID");
    val query = DataQuery()
        .select(customerIDProperty, companyNameProperty, contactNameProperty)
        .from(customersEntitySet)
        .filter(customerIDProperty.equal("ALFKI")
            .or(customerIDProperty.equal("ANATR")));
    val customers = service.executeQuery(query).getEntityList();
    var countOrders = 0;
    L542@
    for (customer in customers)

        L547@
        for (order in orders)
        {
            val orderID = orderIDProperty.getInt(order);
            Example.show("  Order ", Example.formatInt(orderID));
