Class JAXBResult

java.lang.Object
- javax.xml.transform.sax.SAXResult
- - javax.xml.bind.util.JAXBResult

All Implemented Interfaces:: Result

public class JAXBResult
extends SAXResult

JAXP Result implementation that unmarshals a JAXB object.

This utility class is useful to combine JAXB with other Java/XML technologies.

The following example shows how to use JAXB to unmarshal a document resulting from an XSLT transformation.

JAXBResult result = new JAXBResult(
  JAXBContext.newInstance("org.acme.foo") );

// set up XSLT transformation
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer(new StreamSource("test.xsl"));

// run transformation
t.transform(new StreamSource("document.xml"),result);

// obtain the unmarshalled content tree
Object o = result.getResult();

The fact that JAXBResult derives from SAXResult is an implementation detail. Thus in general applications are strongly discouraged from accessing methods defined on SAXResult.

In particular it shall never attempt to call the setHandler, setLexicalHandler, and setSystemId methods.

JAXBResult

public JAXBResult(JAXBContext context)
           throws JAXBException

Creates a new instance that uses the specified JAXBContext to unmarshal.

Parameters:: context - The JAXBContext that will be used to create the necessary Unmarshaller. This parameter must not be null.
Throws:: JAXBException - if an error is encountered while creating the JAXBResult or if the context parameter is null.

JAXBResult

public JAXBResult(Unmarshaller _unmarshaller)
           throws JAXBException

Creates a new instance that uses the specified Unmarshaller to unmarshal an object.

This JAXBResult object will use the specified Unmarshaller instance. It is the caller's responsibility not to use the same Unmarshaller for other purposes while it is being used by this object.

The primary purpose of this method is to allow the client to configure Unmarshaller. Unless you know what you are doing, it's easier and safer to pass a JAXBContext.

Parameters:: _unmarshaller - the unmarshaller. This parameter must not be null.
Throws:: JAXBException - if an error is encountered while creating the JAXBResult or the Unmarshaller parameter is null.

Methods

getResult

public Object getResult()
                 throws JAXBException

Gets the unmarshalled object created by the transformation.

Returns:: Always return a non-null object.
Throws:: IllegalStateException - if this method is called before an object is unmarshalled.; JAXBException - if there is any unmarshalling error. Note that the implementation is allowed to throw SAXException during the parsing when it finds an error.
