    • Method Detail

      • getXPathContext

        public XPathContext getXPathContext()
        Return the XPathContext associated with this XPathExpressionContext. Extensions should use this judiciously and only when special processing requirements cannot be met another way. Consider requesting an enhancement to the ExpressionContext interface to avoid having to call this method.
        Specified by:
        getXPathContext in interface ExpressionContext
        Returns:
        the XPathContext associated with this XPathExpressionContext.
      • getDTMManager

        public DTMManager getDTMManager()
        Return the DTMManager object. Though XPathContext context extends the DTMManager, it really is a proxy for the real DTMManager. If a caller needs to make a lot of calls to the DTMManager, it is faster if it gets the real one from this function.
      • getContextNode

        public org.w3c.dom.Node getContextNode()
        Get the current context node.
        Specified by:
        getContextNode in interface ExpressionContext
        Returns:
        The current context node.
      • getContextNodes

        public org.w3c.dom.traversal.NodeIterator getContextNodes()
        Get the current context node list.
        Specified by:
        getContextNodes in interface ExpressionContext
        Returns:
        An iterator for the current context list, as defined in XSLT.
      • getErrorListener

        public javax.xml.transform.ErrorListener getErrorListener()
        Get the error listener.
        Specified by:
        getErrorListener in interface ExpressionContext
        Returns:
        The registered error listener.
      • toNumber

        public double toNumber​(org.w3c.dom.Node n)
        Get the value of a node as a number.
        Specified by:
        toNumber in interface ExpressionContext
        Parameters:
        n - Node to be converted to a number. May be null.
        Returns:
        value of n as a number.
      • toString

        public java.lang.String toString​(org.w3c.dom.Node n)
        Get the value of a node as a string.
        Specified by:
        toString in interface ExpressionContext
        Parameters:
        n - Node to be converted to a string. May be null.
        Returns:
        value of n as a string, or an empty string if n is null.
      • getVariableOrParam

        public final XObject getVariableOrParam​(QName qname)
                                         throws javax.xml.transform.TransformerException
        Get a variable based on it's qualified name.
        Specified by:
        getVariableOrParam in interface ExpressionContext
        Parameters:
        qname - The qualified name of the variable.
        Returns:
        The evaluated value of the variable.
        Throws:
        javax.xml.transform.TransformerException
