javax.xml.transform
class TransformerFactory

java.lang.Object extended by javax.xml.transform.TransformerFactory
Direct Known Subclasses:
SAXTransformerFactory

Most common way to construct:

TransformerFactory tfactory = TransformerFactory.newInstance();

Based on 413 examples


public abstract class TransformerFactory
extends Object

A TransformerFactory instance can be used to create {@link javax.xml.transform.Transformer} and {@link javax.xml.transform.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. If the property is not defined, a platform default is be used.

getAssociatedStylesheet

public abstract Source getAssociatedStylesheet(Source source,
                                               String media,
                                               String title,
                                               String charset)
                                        throws TransformerConfigurationException

Get the stylesheet specification(s) associated with the XML Source document via the xml-stylesheet processing instruction 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.

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).
title - The value of the title attribute to match. May be null.
charset - The value of the charset attribute to match. May be null.
Returns:
A Source Object suitable for passing to the TransformerFactory.
Throws:
TransformerConfigurationException - An Exception is thrown if an error occurings during parsing of the source.

getAttribute

public abstract Object getAttribute(String name)
Allows the user to retrieve specific attributes on the underlying implementation. An IllegalArgumentException is thrown if the underlying implementation doesn't recognize the attribute.

Parameters:
name - The name of the attribute.
Returns:
value The value of the attribute.

getErrorListener

public abstract ErrorListener getErrorListener()
Get the error event handler for the TransformerFactory.

Returns:
The current error handler, which should never be null.

getFeature

public abstract boolean getFeature(String name)
Look up the value of a feature.

Feature names are fully qualified {@link java.net.URI}s. Implementations may define their own features. false is returned if this TransformerFactory or the Transformers or Templates it creates cannot support the feature. It is possible for an TransformerFactory to expose a feature value but be unable to change its state.

Parameters:
name - Feature name.
Returns:
The current state of the feature, true or false.

getURIResolver

public abstract URIResolver getURIResolver()
Get the object that is used by default during the transformation to resolve URIs used in document(), xsl:import, or xsl:include.

Returns:
The URIResolver that was set with setURIResolver.

newInstance

public static TransformerFactory newInstance()
                                      throws TransformerFactoryConfigurationError

Obtain a new instance of a TransformerFactory. This static method creates a new factory instance This method uses the following ordered lookup procedure to determine the TransformerFactory implementation class to load:

Once an application has obtained a reference to a TransformerFactory it can use the factory to configure and obtain transformer instances.

Returns:
new TransformerFactory instance, never null.
Throws:
TransformerFactoryConfigurationError - Thrown if the implementation is not available or cannot be instantiated.

newInstance

public static TransformerFactory newInstance(String factoryClassName,
                                             ClassLoader classLoader)
                                      throws TransformerFactoryConfigurationError

Obtain a new instance of a TransformerFactory from factory class name. This function is useful when there are multiple providers in the classpath. It gives more control to the application as it can specify which provider should be loaded.

Once an application has obtained a reference to a TransformerFactory it can use the factory to configure and obtain transformer instances.

Tip for Trouble-shooting

Setting the jaxp.debug system property will cause this method to print a lot of debug messages to System.err about what it is doing and where it is looking at.

If you have problems try:

 java -Djaxp.debug=1 YourProgram ....
 

Parameters:
factoryClassName - fully qualified factory class name that provides implementation of javax.xml.transform.TransformerFactory.
classLoader - ClassLoader used to load the factory class. If null current Thread's context classLoader is used to load the factory class.
Returns:
new TransformerFactory instance, never null.
Throws:
TransformerFactoryConfigurationError - if factoryClassName is null, or the factory class cannot be loaded, instantiated.

newTemplates

public abstract 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.

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 - When parsing to construct the Templates object fails.

newTransformer

public abstract Transformer newTransformer()
                                    throws TransformerConfigurationException

Create a new Transformer that performs a copy of the Source to the Result. i.e. the "identity transform".

Returns:
A Transformer object that may be used to perform a transformation in a single thread, never null.
Throws:
TransformerConfigurationException - When it is not possible to create a Transformer instance.

newTransformer

public abstract Transformer newTransformer(Source source)
                                    throws TransformerConfigurationException

Process the Source into a Transformer Object. The Source is an XSLT document that conforms to XSL Transformations (XSLT) Version 1.0. Care must be taken not to use this Transformer in multiple Threads running concurrently. Different TransformerFactories can be used concurrently by different Threads.

Parameters:
source - Source of XSLT document used to create Transformer. Examples of XML Sources include {@link javax.xml.transform.dom.DOMSource DOMSource}, {@link javax.xml.transform.sax.SAXSource SAXSource}, and {@link javax.xml.transform.stream.StreamSource StreamSource}.
Returns:
A Transformer object that may be used to perform a transformation in a single Thread, never null.
Throws:
TransformerConfigurationException - Thrown if there are errors when parsing the Source or it is not possible to create a Transformer instance.

                                  Object value)
Allows the user to set specific attributes on the underlying implementation. An attribute in this context is defined to be an option that the implementation provides. An IllegalArgumentException is thrown if the underlying implementation doesn't recognize the attribute.

Parameters:
name - The name of the attribute.
value - The value of the attribute.

setErrorListener

public abstract void setErrorListener(ErrorListener listener)
Set the error event listener for the TransformerFactory, which is used for the processing of transformation instructions, and not for the transformation itself. An IllegalArgumentException is thrown if the ErrorListener listener is null.

listener - The new error listener.

setFeature

public abstract void setFeature(String name,
                                boolean value)
                         throws TransformerConfigurationException

Set a feature for this TransformerFactory and Transformers or Templates created by this factory.

Feature names are fully qualified {@link java.net.URI}s. Implementations may define their own features. An {@link TransformerConfigurationException} is thrown if this TransformerFactory or the Transformers or Templates it creates cannot support the feature. It is possible for an TransformerFactory to expose a feature value but be unable to change its state.

All implementations are required to support the {@link javax.xml.XMLConstants#FEATURE_SECURE_PROCESSING} feature. When the feature is:

Parameters:
name - Feature name.
value - Is feature state true or false.
Throws:
TransformerConfigurationException - if this TransformerFactory or the Transformers or Templates it creates cannot support this feature.

setURIResolver

public abstract void setURIResolver(URIResolver resolver)
