public Class JDOMSource

extends SAXSource
Class Inheritance
Imports
java.io.*, java.util.*, javax.xml.transform.sax.*, org.jdom.*, org.jdom.output.*, org.xml.sax.*
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);
    }
  }

public Reader getCharacterStream()

Overrides org.xml.sax.InputSource.getCharacterStream.

Returns the source.

Returns:Object

the source as a JDOM document or a list of JDOM nodes.

public void setByteStream(InputStream byteStream) throws UnsupportedOperationException

Overrides org.xml.sax.InputSource.setByteStream.

Sets the byte stream for this input source.

This implementation always throws an UnsupportedOperationException as the only source stream supported is the source JDOM document.

setCharacterStreamback to summary
public void setCharacterStream(Reader characterStream) throws UnsupportedOperationException

Overrides org.xml.sax.InputSource.setCharacterStream.
