Class TransformerFactoryImpl


  • public class TransformerFactoryImpl
    extends SAXTransformerFactory
    A TransformerFactoryImpl instance can be used to create Transformer and Template objects.

    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.

    • Method Detail

      • newTransformer

        public Transformer newTransformer​(Source source)
                                   throws TransformerConfigurationException
        Process the Source into a Transformer object. Care must be given not to use this object in multiple threads running concurrently. Different TransformerFactories can be used concurrently by different threads.
        Specified by:
        newTransformer in class TransformerFactory
        Parameters:
        source - An object that holds a URI, input stream, etc.
        Returns:
        A Transformer object that may be used to perform a transformation in a single thread, never null.
        Throws:
        TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.
      • newTemplates

        public Templates newTemplates​(Source source)
                               throws TransformerConfigurationException
        Process the Source into a Templates object, which is a a compiled representation of the source. This Templates object may then be used concurrently across multiple threads. Creating a Templates object allows the TransformerFactory to do detailed performance optimization of transformation instructions, without penalizing runtime transformation.
        Specified by:
        newTemplates in class TransformerFactory
        Parameters:
        source - An object that holds a URL, input stream, etc.
        Returns:
        A Templates object capable of being used for transformation purposes, never null.
        Throws:
        TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.
      • getSAXSource

        public SAXSource getSAXSource​(Source source,
                                      boolean isStyleSheet)
        Convert a supplied Source to a SAXSource
        Parameters:
        source - The supplied input source
        isStyleSheet - true if the source is a stylesheet
        Returns:
        a SAXSource

                                              String title,
                                              String charset)
                                       throws TransformerConfigurationException
        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. Note that it is possible to return several stylesheets, in which case they are applied as if they were a list of imports or cascades.
        Specified by:
        getAssociatedStylesheet in class TransformerFactory
        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).
        title - The value of the title attribute to match. May be null.
        charset - The value of the charset attribute to match. May be null.
        Returns:
        A Source object suitable for passing to the TransformerFactory.
        Throws:
        TransformerConfigurationException
      • compositeStylesheet

                                   throws TransformerConfigurationException
        Process a series of stylesheet inputs, treating them in import or cascade order. This is mainly for support of the getAssociatedStylesheets method, but may be useful for other purposes.
        Parameters:
        sources - An array of SAX InputSource objects.
        Returns:
        A Source object representing a composite stylesheet.

        Set an object that is used by default during the transformation to resolve URIs used in xsl:import, or xsl:include.
        Specified by:
        setURIResolver in class TransformerFactory
        Parameters:
        resolver - An object that implements the URIResolver interface, or null.
      • getURIResolver

        getURIResolver in class TransformerFactory
        Returns:
        The URIResolver that was set with setURIResolver.
      • 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.

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

        The Saxon implementation does not support the secure processing feature.

        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.

      • getFeature

        public boolean getFeature​(String name)
        Look up the value of a feature.

        The feature name is any absolute URI.

        Specified by:
        getFeature in class TransformerFactory
        Parameters:
        name - The feature name, which is an absolute URI.

                          throws IllegalArgumentException
        Allows the user to set specific attributes on the underlying implementation. An attribute in this context is defined to be an option that the implementation provides.
        Specified by:
        setAttribute in class TransformerFactory
        Parameters:
        name - The name of the attribute. This must be one of the constants defined in class FeatureKeys.
        value - The value of the attribute.
