Class TransformerImpl


public class TransformerImpl extends AbstractTransformerImpl
Saxon implementation of the JAXP Transformer interface.

Since Saxon 9.6, JAXP interfaces are implemented as a layer above the s9api interface

    • transform

      public void transform(Source xmlSource, Result outputTarget) throws XPathException

      Transform the XML Source to a Result. Specific transformation behavior is determined by the settings of the TransformerFactory in effect when the Transformer was instantiated and any modifications made to the Transformer instance.

      An empty Source is represented as an empty document as constructed by DocumentBuilder.newDocument(). The result of transforming an empty Source depends on the transformation behavior; it is not always an empty Result.

      Overrides:
      transform in class IdentityTransformer
      Parameters:
      xmlSource - The XML input to transform.
      outputTarget - The Result of transforming the xmlSource.
      Throws:
      XPathException - If an unrecoverable error occurs during the course of the transformation.
    • setConvertedParameter

      protected void setConvertedParameter(QName name, XdmValue value)
      Specified by:
      setConvertedParameter in class AbstractTransformerImpl
    • clearParameters

      public void clearParameters()
      Clear all parameters set with setParameter.
      Overrides:
      clearParameters in class AbstractTransformerImpl
    • setURIResolver

      public void setURIResolver(URIResolver resolver)
      Set an object that will be used to resolve URIs used in document().

      If the resolver argument is null, the URIResolver value will be cleared and the transformer will no longer have a resolver.

      Overrides:
      setURIResolver in class IdentityTransformer
      Parameters:
      resolver - An object that implements the URIResolver interface, or null.
    • setErrorListener

      public void setErrorListener(ErrorListener listener) throws IllegalArgumentException
      Set the error event listener in effect for the transformation.
      Overrides:
      setErrorListener in class IdentityTransformer
      Parameters:
      listener - The new error listener.
      Throws:
      IllegalArgumentException - if listener is null.
    • setInitialTemplate

      public void setInitialTemplate(String name)
      Supply an initial template for a transformation.

      This is a Saxon extension to the JAXP interface, needed for XSLT 2.0

      Changed in 9.9 so it no longer validates the supplied name; an incorrect name will lead to an error later.

      Parameters:
      name - the name of the initial template, in Clark notation (either a local name, or "{uri}local")
    • setInitialMode

      public void setInitialMode(String name) throws IllegalArgumentException
      Supply an initial mode for a transformation.

      This is a Saxon extension to the JAXP interface, needed for XSLT 2.0

      Parameters:
      name - the name of the initial mode, in Clark notation (either a local name, or "{uri}local")
      Throws:
      IllegalArgumentException - if the argument is invalid, for example if the format of the name is incorrect or if there is no mode with this name
    • getUnderlyingXsltTransformer

      public XsltTransformer getUnderlyingXsltTransformer()
      Get the underlying s9api implementation class wrapped by this JAXP Transformer
      Returns:
      the underlying s9api XsltTransformer
    • getUnderlyingController

      public XsltController getUnderlyingController()
      Get the internal Saxon Controller instance that implements this transformation. Note that the Controller interface will not necessarily remain stable in future releases
      Specified by:
      getUnderlyingController in class AbstractTransformerImpl
      Returns:
      the underlying Saxon Controller instance
    • newTransformerHandler

      public TransformerHandler newTransformerHandler()
      Create a JAXP TransformerHandler to perform the transformation
      Returns:
      a JAXP TransformerHandler, which allows the transformation to be performed in "push" mode on a SAX pipeline.
    • newXMLFilter

      public XMLFilter newXMLFilter()
      Create a JAXP XMLFilter which allows this transformation to be added to a SAX pipeline
      Specified by:
      newXMLFilter in class AbstractTransformerImpl
      Returns:
      the transformation in the form of an XMLFilter
    • reset

      public void reset()
      Description copied from class: IdentityTransformer

      Reset this Transformer to its original configuration.

      Transformer is reset to the same state as when it was created with TransformerFactory.newTransformer(), TransformerFactory.newTransformer(javax.xml.transform.Source source) or Templates.newTransformer(). reset() is designed to allow the reuse of existing Transformers thus saving resources associated with the creation of new Transformers.

      The reset Transformer is not guaranteed to have the same URIResolver or ErrorListener Objects, e.g. Object.equals(Object obj). It is guaranteed to have a functionally equal URIResolver and ErrorListener.

      Overrides:
      reset in class IdentityTransformer
