4.42. Java Binding Example

This Order message example shows how to bind it into a corresponding Java Object model.
The message input: 
<order xmlns="http://x">
    <header>
        <y:date xmlns:y="http://y">Wed Nov 15 13:45:28 EST 2006</y:date>
        <customer number="123123">Joe</customer>
        <privatePerson></privatePerson>
    </header>
    <order-items>
        <order-item>
            <product>111</product>
            <quantity>2</quantity>
            <price>8.90</price>
        </order-item>
        <order-item>
            <product>222</product>
            <quantity>7</quantity>
            <price>5.20</price>
        </order-item>
    </order-items>
</order>
The Java Model (not including getters/setters): 
public class Order {
    private Header header;
    private List<OrderItem> orderItems;
}
 
public class Header {
    private Long customerNumber;
    private String customerName;
}
 
public class OrderItem {
    private long productId;
    private Integer quantity;
    private double price;
}
The configuration code: 
  
Smooks smooks = new Smooks();
 
Bean orderBean = new Bean(Order.class, "order", "/order");
 
orderBean.bindTo("header",
    orderBean.newBean(Header.class, "/order")
        .bindTo("customerNumber", "header/customer/@number")
        .bindTo("customerName", "header/customer")
    ).bindTo("orderItems",
    orderBean.newBean(ArrayList.class, "/order")
        .bindTo(orderBean.newBean(OrderItem.class, "order-item")
            .bindTo("productId", "order-item/product")
            .bindTo("quantity", "order-item/quantity")
            .bindTo("price", "order-item/price"))
    );
 
smooks.addVisitors(orderBean);
The execution code: 
 JavaResult result = new JavaResult();
 
smooks.filterSource(new StreamSource(orderMessageStream), result);
Order order = (Order) result.getBean("order");
Here is an example where an anonymous Factory class is defined and used: 
Bean orderBean = new Bean(Order.class, "order", "/order", new Factory<Order>() {
 
 public Order create(ExecutionContext executionContext) {
  return new Order();
 }
 
});
