public class JXSAXTransformerFactory

extends SAXTransformerFactory

A JXTransformerFactory instance can be used to create Transformer and Templates objects.

The system property that determines which Factory implementation to create is named "javax.xml.transform.TransformerFactory". This property names a concrete subclass of the TransformerFactory abstract class (in our case, it is JXSAXTransformerFactory). If the property is not defined, a platform default is be used.

This class also provides SAX-specific factory methods. It provides two types of ContentHandlers, one for creating Transformers, the other for creating Templates objects.

If an application wants to set the ErrorHandler or EntityResolver for an XMLReader used during a transformation, it should use a URIResolver to return the SAXSource which provides (with getXMLReader) a reference to the XMLReader.

newTemplatesHandler in class SAXTransformerFactory

Returns:

A non-null reference to a TransformerHandler, that may be used as a ContentHandler for SAX parse events.

TransformerConfigurationException - If for some reason the TemplatesHandler cannot be created.

newXMLFilter

public XMLFilter newXMLFilter(Source src)
                       throws TransformerConfigurationException

Create an XMLFilter that uses the given Source as the transformation instructions.

Specified by:

newXMLFilter in class SAXTransformerFactory

Parameters:

src - The Source of the transformation instructions.

Returns:

An XMLFilter object, or null if this feature is not supported.

Throws:

TransformerConfigurationException - If for some reason the TemplatesHandler cannot be created.

newXMLFilter

public XMLFilter newXMLFilter(Templates templates)
                       throws TransformerConfigurationException

Create an XMLFilter, based on the Templates argument..

Specified by:

newXMLFilter in class SAXTransformerFactory

Parameters:

templates - The compiled transformation instructions.

Returns:

An XMLFilter object, or null if this feature is not supported.

Throws:

TransformerConfigurationException - If for some reason the TemplatesHandler cannot be created.

newTransformer

public Transformer newTransformer(Source source)
                           throws TransformerConfigurationException

Process the Source into a Transformer object. Care must be given not to use this object in multiple threads running concurrently. Different TransformerFactories can be used concurrently by different threads.

Specified by:

newTransformer in class TransformerFactory

Parameters:

source - An object that holds a URI, input stream, etc.

Returns:

A Transformer object that may be used to perform a transformation in a single thread, never null.

Throws:

TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.

newTransformer

public Transformer newTransformer()
                           throws TransformerConfigurationException

Create a new Transformer object that performs a copy of the source to the result.

Specified by:

newTransformer in class TransformerFactory

Returns:

A Transformer object that may be used to perform a transformation in a single thread, never null.

Throws:

TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.

newTemplates

public Templates newTemplates(Source source)
                       throws TransformerConfigurationException

Process the Source into a Templates object, which is a a compiled representation of the source. This Templates object may then be used concurrently across multiple threads. Creating a Templates object allows the TransformerFactory to do detailed performance optimization of transformation instructions, without penalizing runtime transformation.

Specified by:

newTemplates in class TransformerFactory

Parameters:

source - An object that holds a URL, input stream, etc.

Returns:

A Templates object capable of being used for transformation purposes, never null.

Throws:

TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.

getAssociatedStylesheet

public Source getAssociatedStylesheet(Source source,
                                      java.lang.String media,
                                      java.lang.String title,
                                      java.lang.String charset)
                               throws TransformerConfigurationException

Get the stylesheet specification(s) associated via the xml-stylesheet processing instruction (see http://www.w3.org/TR/xml-stylesheet/) with the document document specified in the source parameter, and that match the given criteria. Note that it is possible to return several stylesheets, in which case they are applied as if they were a list of imports or cascades in a single stylesheet.

Specified by:

getAssociatedStylesheet in class TransformerFactory

Parameters:

source - The XML source document.

media - The media attribute to be matched. May be null, in which case the prefered templates will be used (i.e. alternate = no).

charset - The value of the charset attribute to match. May be null.

Returns:

A Source object suitable for passing to the TransformerFactory.

Throws:

TransformerConfigurationException.
