/**
 * {@link com.sun.xml.ws.client.sei.MethodHandler} that handles synchronous method invocations.
 *  This is refactored from SEIMethodHandler.
 * 

* This class mainly performs the following two tasks: *

    *
  1. Accepts Object[] that represents arguments for a Java method, * and creates {@link com.sun.xml.ws.message.jaxb.JAXBMessage} that represents a request message. *
  2. Takes a {@link com.sun.xml.ws.api.message.Message} that represents a response, * and extracts the return value (and updates {@link javax.xml.ws.Holder }s.) *
* *

Creating {@link com.sun.xml.ws.message.jaxb.JAXBMessage }

*

* At the construction time, we prepare {@link com.sun.xml.ws.client.sei.BodyBuilder} and {@link com.sun.xml.ws.client.sei.MessageFiller}s * that know how to move arguments into a {@link com.sun.xml.ws.api.message.Message }. * Some arguments go to the payload, some go to headers, still others go to attachments. * * @author Kohsuke Kawaguchi * @author Jitendra Kotamraju * @author [email protected] */ public class StubHandler implements ClientCallBridge { // these objects together create a message from method parameters private final BodyBuilder bodyBuilder;
