Class TransformerFactory


java.lang.Object

  |

public abstract class TransformerFactory
extends java.lang.Object

A TransformerFactory instance can be used to create Transformer and Template objects.

The system property that determines which Factory implementation property names a concrete subclass of the TransformerFactory abstract class. If the property is not defined, a platform default is be used.

          Default constructor is protected on purpose.

Constructor Summary

protected

          Allows the user to retrieve specific attributes on the underlying implementation.
          Look up the value of a feature. java.lang.Object value)
          Allows the user to set specific attributes on the underlying implementation.
          Set the error event listener for the TransformerFactory, which is used for the processing of transformation instructions, and not for the transformation itself.
          Set an object that is used by default during the transformation to resolve URIs used in xsl:import, or xsl:include.

Method Detail

newInstance





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:
 
 
 property.
 
 
 Use the JAVA_HOME(the parent directory where jdk is
 installed)/lib/jaxp.properties for a property file that contains the
 name of the implementation class keyed on the same value as the
 system property defined above.
 
 
 Use the Services API (as detailed in the JAR specification), if
 available, to determine the classname. The Services API will look
 for a classname in the file
 in jars available to the runtime.
 
 
 Platform default TransformerFactory instance.
 
 

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












newTransformer





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.


Parameters:
source - An object that holds a URI, input stream, etc.
Returns:
A Transformer object that may be used to perform a transformation
            when it is constructing the Templates object and fails.











newTransformer





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


Parameters:
source - An object that holds a URI, input stream, etc.
Returns:
A Transformer object that may be used to perform a transformation
            the parse when it is constructing the
            Templates object and fails.










newTemplates





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,
            is constructing the Templates object and fails.










getAssociatedStylesheet


                                               java.lang.String media,
                                               java.lang.String title,
                                               java.lang.String charset)



Get the stylesheet specification(s) associated
 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.


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. -  










setURIResolver





Set an object that is used by default during the transformation
 to resolve URIs used in xsl:import, or xsl:include.


Parameters:
resolver - An object that implements the URIResolver interface,
 or null.











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.











getFeature


public abstract boolean getFeature(java.lang.String name)



Look up the value of a feature.

 The feature name is any absolute URI.


Parameters:
name - The feature name, which is an absolute URI.
Returns:
The current state of the feature (true or false).











setAttribute


public abstract void setAttribute(java.lang.String name,
                                  java.lang.Object value)
                           throws java.lang.IllegalArgumentException



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.


Parameters:
name - The name of the attribute.
value - The value of the attribute.
Throws:
java.lang.IllegalArgumentException - thrown if the underlying
 implementation doesn't recognize the attribute.











getAttribute


public abstract java.lang.Object getAttribute(java.lang.String name)
                                       throws java.lang.IllegalArgumentException



Allows the user to retrieve specific attributes on the underlying
 implementation.


Parameters:
name - The name of the attribute.
Returns:
value The value of the attribute.
Throws:
java.lang.IllegalArgumentException - thrown if the underlying
 implementation doesn't recognize the attribute.










setErrorListener


                               throws java.lang.IllegalArgumentException



Set the error event listener for the TransformerFactory, which
 is used for the processing of transformation instructions,
 and not for the transformation itself.


Parameters:
listener - The new error listener.
Throws:
java.lang.IllegalArgumentException - if listener is null.











getErrorListener





Get the error event handler for the TransformerFactory.


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