      • prepareAttributes

        public void prepareAttributes()
                               throws javax.xml.transform.TransformerConfigurationException
        Description copied from class: StyleElement
        Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass
        Specified by:
        prepareAttributes in class StyleElement
        Throws:
        javax.xml.transform.TransformerConfigurationException
      • validate

        public void validate()
                      throws javax.xml.transform.TransformerConfigurationException
        Description copied from class: StyleElement
        Check that the element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.
        Overrides:
        validate in class StyleElement
        Throws:
        javax.xml.transform.TransformerConfigurationException
      • preprocess

        public void preprocess()
                        throws javax.xml.transform.TransformerConfigurationException
        Description copied from class: StyleElement
        Default preprocessing method does nothing. It is implemented for those top-level elements that can be evaluated before the source document is available, for example xsl:key, xsl:attribute-set, xsl:template, xsl:locale
        Overrides:
        preprocess in class StyleElement
        Throws:
        javax.xml.transform.TransformerConfigurationException
      • process

        public void process​(Context context)
                     throws javax.xml.transform.TransformerException
        Description copied from class: StyleElement
        Process: called to do the real work of this stylesheet element. This method must be implemented in each subclass.
        Specified by:
        process in class StyleElement
        Parameters:
        context - The context in the source XML document, giving access to the current node, the current variables, etc.
        Throws:
        javax.xml.transform.TransformerException
      • bindVariable

        public Binding bindVariable​(int fingerprint)
                             throws XPathException
        Disallow variable references in the match and use patterns
        Overrides:
        bindVariable in class StyleElement
        Parameters:
        fingerprint - The fingerprint of the name of the variable
        Returns:
        a Binding for the variable
        Throws:
        XPathException - if the variable has not been declared
