Class SaxonTransformerFactory

  • All Implemented Interfaces:
    Configuration.ApiProvider
    Direct Known Subclasses:
    TransformerFactoryImpl
    public class SaxonTransformerFactory
extends javax.xml.transform.sax.SAXTransformerFactory
implements Configuration.ApiProvider
    A SaxonTransformerFactory instance can be used to create Transformer and Template objects.

    Although the class is public, it is not intended to be used directly by applications; applications should normally invoke the subclass TransformerFactoryImpl.

    The system property that determines which Factory implementation to create is named "javax.xml.transform.TransformerFactory". This property names a concrete subclass of the TransformerFactory abstract class. If the property is not defined, a platform default is be used.

    This implementation class implements the abstract methods on both the javax.xml.transform.TransformerFactory and javax.xml.transform.sax.SAXTransformerFactory classes.

    Since Saxon 9.6, the JAXP transformation interface is re-implemented as a layer on top of the s9api interface. This will affect applications that attempt to down-cast from JAXP interfaces to the underlying implementation classes.

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

        This method is defined in JAXP but its use with Saxon is deprecated, because the errorListener will be shared by all stylesheet compilations running under this factory, which may be operating concurrently in different threads.

        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.

        All implementations are required to support the FEATURE_SECURE_PROCESSING feature. When the feature is:

        • true: the implementation will limit XML processing to conform to implementation limits and behave in a secure fashion as defined by the implementation. Examples include resolving user defined style sheets and functions. If XML processing is limited for security reasons, it will be reported via a call to the registered ErrorListener.fatalError(javax.xml.transform.TransformerException exception). See setErrorListener(javax.xml.transform.ErrorListener listener). In the Saxon implementation, this option causes calls on extension functions and extensions instructions to be disabled, and also disables the use of xsl:result-document to write to secondary output destinations.
        • false: the implementation will processing XML according to the XML specifications without regard to possible implementation limits.
        Specified by:
        setFeature in class javax.xml.transform.TransformerFactory
        Parameters:
        name - Feature name.
        value - Is feature state true or false.
        Throws:
        javax.xml.transform.TransformerConfigurationException - if this TransformerFactory or the Transformers or Templates it creates cannot support this feature.
        java.lang.NullPointerException - If the name parameter is null.
