Class ValueBinder

java.lang.Object

org.milyn.javabean.ValueBinder

All Implemented Interfaces:

ContentHandler, DOMElementVisitor, DOMVisitAfter, DOMVisitBefore, DOMVisitor, Producer, SAXVisitAfter, SAXVisitBefore, SAXVisitor, Visitor

public class ValueBinder
extends Object
implements DOMElementVisitor, SAXVisitBefore, SAXVisitAfter, Producer

Value Binder. This class can be used to configure a Smooks instance for creating value objects using the Smooks DataDecoders.

XML Schema & Namespace

The Value Binder XML configuration schema is in the following XML Schema Namespace: http://www.milyn.org/xsd/smooks/javabean-1.3.xsd The value binder element is '<value>'. Take a look in the schema for all the configuration attributes.

Programmatic configuration

The value binder can be programmatic configured using the Value Object.

Example

Taking the "classic" Order message as an example and getting the order number and name as Value Objects in the form of an Integer and String.

The Message

 <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-items>
 </order>
