    • 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.

      Specified by:
      setFeature in class TransformerFactory
      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.
      Specified by:
      getFeature in class TransformerFactory
      Parameters:
      name - The feature name
      Returns:
      'true' if feature is supported, 'false' if not

    • 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
