Class org.jdom.transform.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);
     }
   }

Variable Index

 o JDOM_FEATURE
If {

Constructor Index

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

Method Index

 o getDocument()
Returns the source document used by this TRaX source.
 o getXMLReader()
Returns the XMLReader to be used for the Source.
 o setDocument(Document)
Sets the source document used by this TRaX source.
 o setInputSource(InputSource)
Sets the SAX InputSource to be used for the Source.
 o setXMLReader(XMLReader)
Set the XMLReader to be used for the Source.

Variables

 o JDOM_FEATURE
 public static final String JDOM_FEATURE
If {@link 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 {@link SAXSource#FEATURE} value defined by its superclass to be considered as a SAXSource by Transformer implementations not natively supporting JDOM.

Constructors

 o 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:
setDocument

Methods

 o 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:
getDocument
 o 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:
setDocument
 o setInputSource
 public void setInputSource(InputSource inputSource) throws UnsupportedOperationException
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 {@link UnsupportedOperationException}.

Parameters:
inputSource - a valid InputSource reference.
Throws: UnsupportedOperationException
always!
Overrides:
setInputSource in class SAXSource
 o setXMLReader
 public void setXMLReader(XMLReader reader) throws UnsupportedOperationException
Set the XMLReader to be used for the Source.

As this implementation only supports JDOM document as data source, this method throws an {@link UnsupportedOperationException} if the provided reader object does not implement the SAX {@link 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!
Overrides:
setXMLReader in class SAXSource
See Also:
getXMLReader
 o 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.
Overrides:
getXMLReader in class SAXSource
