                      throws IllegalArgumentException

javax.xml.transform.sax.TransformerFactory implementation. 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 error listener to use with the TransformerFactory

Throws:

IllegalArgumentException

getErrorListener

public ErrorListener getErrorListener()

javax.xml.transform.sax.TransformerFactory implementation. Get the error event handler for the TransformerFactory.

Returns:

The error listener used with the TransformerFactory

getAttribute

public Object getAttribute(String name)
                    throws IllegalArgumentException

javax.xml.transform.sax.TransformerFactory implementation. Returns the value set for a TransformerFactory attribute

Parameters:

name - The attribute name

Returns:

An object representing the attribute value

Throws:

IllegalArgumentException

setAttribute

public void setAttribute(String name,
                         Object value)
                  throws IllegalArgumentException

javax.xml.transform.sax.TransformerFactory implementation. Sets the value for a TransformerFactory attribute.

Parameters:

name - The attribute name

value - An object representing the attribute value

IllegalArgumentException

setFeature

public 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 URIs. Implementations may define their own features. An 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.

See TransformerFactory for full documentation of specific features.

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.

NullPointerException - If the name parameter is null.

getFeature

public boolean getFeature(String name)

javax.xml.transform.sax.TransformerFactory implementation. Look up the value of a feature (to see if it is supported). This method must be updated as the various methods and features of this class are implemented.

Parameters:

name - The feature name

Returns:

'true' if feature is supported, 'false' if not

getURIResolver

public URIResolver getURIResolver()

javax.xml.transform.sax.TransformerFactory implementation. Get the object that is used by default during the transformation to resolve URIs used in document(), xsl:import, or xsl:include.

Returns:

The URLResolver used for this TransformerFactory and all Templates and Transformer objects created using this factory

setURIResolver

public void setURIResolver(URIResolver resolver)

javax.xml.transform.sax.TransformerFactory implementation. Set the object that is used by default during the transformation to resolve URIs used in document(), xsl:import, or xsl:include. Note that this does not affect Templates and Transformers that are already created with this factory.

Parameters:

resolver - The URLResolver used for this TransformerFactory and all Templates and Transformer objects created using this factory

getAssociatedStylesheet

public Source getAssociatedStylesheet(Source source,
                                      String media,

                               throws TransformerConfigurationException

javax.xml.transform.sax.TransformerFactory implementation. 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.

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).

TransformerConfigurationException

error

public void error(TransformerException e)
           throws TransformerException

Receive notification of a recoverable error. The transformer must continue to provide normal parsing events after invoking this method. It should still be possible for the application to process the document through to the end.

Specified by:

error in interface ErrorListener

Parameters:

e - The warning information encapsulated in a transformer exception.

Throws:

TransformerException - if the application chooses to discontinue the transformation (always does in our case).

fatalError

public void fatalError(TransformerException e)
                throws TransformerException

Receive notification of a non-recoverable error. The application must assume that the transformation cannot continue after the Transformer has invoked this method, and should continue (if at all) only to collect addition error messages. In fact, Transformers are free to stop reporting events once this method has been invoked.

Specified by:

fatalError in interface ErrorListener

Parameters:

e - warning information encapsulated in a transformer exception.

Throws:

TransformerException - if the application chooses to discontinue the transformation (always does in our case).

warning

public void warning(TransformerException e)
             throws TransformerException

Receive notification of a warning. Transformers can use this method to report conditions that are not errors or fatal errors. The default behaviour is to take no action. After invoking this method, the Transformer must continue with the transformation. It should still be possible for the application to process the document through to the end.

Specified by:

warning in interface ErrorListener

Parameters:

e - The warning information encapsulated in a transformer exception.

Throws:

TransformerException - if the application chooses to discontinue the transformation (never does in our case).

loadSource

public InputSource loadSource(String href,
                              String context,
                              XSLTC xsltc)

This method implements XSLTC's SourceLoader interface. It is used to glue a TrAX URIResolver to the XSLTC compiler's Input and Import classes.

Specified by:

loadSource in interface SourceLoader

Parameters:

href - The URI of the document to load

context - The URI of the currently loaded document

xsltc - The compiler that resuests the document

Returns:

An InputSource with the loaded document
