### setParameter

    public void setParameter(java.lang.String name,
                             java.lang.Object value)

  Implements JAXP's Transformer.setParameter() Add a parameter for the transformation. The parameter is simply passed on to the translet - no validation is performed - so any unused parameters are quitely ignored by the translet.
  Parameters:
    `name` - The name of the parameter
    `value` - The value to assign to the parameter
  Overrides:
    setParameter in class Transformer

### clearParameters

    public void clearParameters()

  Implements JAXP's Transformer.clearParameters() Clear all parameters set with setParameter. Clears the translet's parameter stack.
  Overrides:
    clearParameters in class Transformer

### getParameter

    public final java.lang.Object getParameter(java.lang.String name)

  Implements JAXP's Transformer.getParameter() Returns the value of a given parameter. Note that the translet will not keep values for parameters that were not defined in the stylesheet.
  Parameters:
    `name` - The name of the parameter
  Returns:
    An object that contains the value assigned to the parameter
  Overrides:
    getParameter in class Transformer

### getURIResolver

    public URIResolver getURIResolver()

  Implements JAXP's Transformer.getURIResolver() Set the object currently used to resolve URIs used in document().
  Returns:
    The URLResolver object currently in use
  Overrides:
    getURIResolver in class Transformer

### setURIResolver

    public void setURIResolver(URIResolver resolver)

  Implements JAXP's Transformer.setURIResolver() Set an object that will be used to resolve URIs used in document().
  Parameters:
    `resolver` - The URIResolver to use in document()
  Overrides:
    setURIResolver in class Transformer

### retrieveDocument

    public DOM retrieveDocument(java.lang.String baseURI,
                                java.lang.String href,
                                Translet translet)

  This class should only be used as a DOMCache for the translet if the URIResolver has been set. The method implements XSLTC's DOMCache interface, which is used to plug in an external document loader into a translet. This method acts as an adapter between TrAX's URIResolver interface and XSLTC's DOMCache interface. This approach is simple, but removes the possibility of using external document caches with XSLTC.
  Specified by:
    retrieveDocument in interface DOMCache
  Parameters:
    `baseURI` - The base URI used by the document call.
    `href` - The href argument passed to the document function.
    `translet` - A reference to the translet requesting the document

### 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` - The 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).

### reset

    public void reset()

  This method resets the Transformer to its original configuration Transformer code is reset to the same state it was when it was created
  Overrides:
    reset in class Transformer
  Since:
    1.5
