Class JDOMSource

public class JDOMSource extends SAXSource

Acts as an holder for JDOM document sources.

This class shall be used to wrap a JDOM Document to provide it as input to a JAXP Transformer

The following example shows how to apply an XSL Transformation to a JDOM document and get the transformation result in the form of another JDOM Document:

   public static Document transform(Document in, String stylesheet)
                                        throws JDOMException {
     try {
       Transformer transformer = TransformerFactory.newInstance()
          .newTransformer(new StreamSource(stylesheet));

       JDOMResult out = new JDOMResult();
       transformer.transform(new JDOMSource(in), out);
       return out.getDocument();
     }
     catch (TransformerException e) {
       throw new JDOMException("XSLT Trandformation failed", e);
     }
   }

Field Detail

JDOM_FEATURE

public static final String JDOM_FEATURE
If javax.xml.transform.TransformerFactory#getFeature returns true when passed this value as an argument, the Transformer natively supports JDOM.

Note: This implementation does not override the SAXSource#FEATURE value defined by its superclass to be considered as a SAXSource by Transformer implementations not natively supporting JDOM.

Constructor Detail

JDOMSource

public JDOMSource(Document source)
Creates a JDOM TRaX source wrapping a JDOM document.

Parameters: source the JDOM document to use as source for the transformations

Throws: NullPointerException if source is null.

See Also: JDOMSource

Method Detail

getDocument

public Document getDocument()
Returns the source document used by this TRaX source.

Returns: the source document used by this TRaX source or null if none has been set.

See Also: JDOMSource

getXMLReader

public XMLReader getXMLReader()
Returns the XMLReader to be used for the Source.

This implementation returns a specific XMLReader reading the XML data from the source JDOM document.

Returns: an XMLReader reading the XML data from the source JDOM document.

setDocument

public void setDocument(Document source)
Sets the source document used by this TRaX source.

Parameters: source the JDOM document to use as source for the transformations

Throws: NullPointerException if source is null.

See Also: JDOMSource

setInputSource

public void setInputSource(InputSource inputSource)
Sets the SAX InputSource to be used for the Source.

As this implementation only supports JDOM document as data source, this method always throws an UnsupportedOperationException.

Parameters: inputSource a valid InputSource reference.

Throws: UnsupportedOperationException always!

setXMLReader

public void setXMLReader(XMLReader reader)
Set the XMLReader to be used for the Source.

As this implementation only supports JDOM document as data source, this method throws an UnsupportedOperationException if the provided reader object does not implement the SAX XMLFilter interface. Otherwise, the JDOM document reader will be attached as parent of the filter chain.

Parameters: reader a valid XMLReader or XMLFilter reference.

Throws: UnsupportedOperationException always!
