Class JDOMSource

java.lang.Object
  javax.xml.transform.sax.SAXSource
      org.jdom.transform.JDOMSource

All Implemented Interfaces:

javax.xml.transform.Source

public class JDOMSource
extends javax.xml.transform.sax.SAXSource

A holder for an XML Transformation source: a Document, Element, or list of nodes.

The is provides input to a JAXP TrAX Transformer.

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

   public static List transform(Document doc, String stylesheet)
                                        throws JDOMException {
     try {
       Transformer transformer = TransformerFactory.newInstance()
                             .newTransformer(new StreamSource(stylesheet));
       JDOMSource in = new JDOMSource(doc);
       JDOMResult out = new JDOMResult();
       transformer.transform(in, out);
       return out.getResult();
     }
     catch (TransformerException e) {
       throw new JDOMException("XSLT Transformation failed", e);
     }
   }

Field Detail

JDOM_FEATURE

public static final java.lang.String JDOM_FEATURE

If TransformerFactory.getFeature(java.lang.String) 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:

java.lang.IllegalArgumentException - if source is null.

JDOMSource

public JDOMSource(java.util.List source)

Creates a JDOM TrAX source wrapping a list of JDOM nodes.

Parameters:

source - the JDOM nodes to use as source for the transformations

Throws:

java.lang.IllegalArgumentException - if source is null.

JDOMSource

public JDOMSource(Element source)

Creates a JDOM TrAX source wrapping a JDOM element.

Parameters:

source - the JDOM element to use as source for the transformations

Throws:

java.lang.IllegalArgumentException - if source is null.

JDOMSource

public JDOMSource(Document source,
                  org.xml.sax.EntityResolver resolver)

Creates a JDOM TrAX source wrapping a JDOM element with an associated EntityResolver to resolve external entities.

Parameters:

source - The JDOM Element to use as source for the transformations

resolver - Entity resolver to use for the source transformation

Throws:

java.lang.IllegalArgumentException - ifsource is null

Method Detail

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:

java.lang.IllegalArgumentException - if source is null.

See Also:

getDocument()

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 the source is a node list.

See Also:

setDocument(org.jdom.Document)

setNodes

public void setNodes(java.util.List source)

Sets the source node list used by this TrAX source.

Parameters:

source - the JDOM nodes to use as source for the transformations

Throws:

java.lang.IllegalArgumentException - if source is null.

See Also:

getNodes()

getNodes

public java.util.List getNodes()

Returns the source node list used by this TrAX source.

Returns:

the source node list used by this TrAX source or null if the source is a JDOM document.

See Also:

setDocument(org.jdom.Document)

setInputSource

public void setInputSource(org.xml.sax.InputSource inputSource)
                    throws java.lang.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 UnsupportedOperationException.

Overrides:

setInputSource in class javax.xml.transform.sax.SAXSource

Parameters:

inputSource - a valid InputSource reference.

Throws:

java.lang.UnsupportedOperationException - always!

setXMLReader

public void setXMLReader(org.xml.sax.XMLReader reader)
                  throws java.lang.UnsupportedOperationException

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.

Overrides:

setXMLReader in class javax.xml.transform.sax.SAXSource

Parameters:

reader - a valid XMLReader or XMLFilter reference.

Throws:

java.lang.UnsupportedOperationException - if reader is not a SAX XMLFilter.

See Also:

getXMLReader()

getXMLReader

public org.xml.sax.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.

Overrides:

getXMLReader in class javax.xml.transform.sax.SAXSource

Returns:

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