      • evaluateItem

        public Item evaluateItem​(XPathContext c)
                          throws XPathException
        Evaluate the function
        Overrides:
        evaluateItem in class Expression
        Parameters:
        c - The context in which the expression is to be evaluated
        Returns:
        the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence
        Throws:
        XPathException - if any dynamic error occurs evaluating the expression
      • getNilledProperty

        public static BooleanValue getNilledProperty​(NodeInfo node)
        Determine whether a node has the nilled property
        Parameters:
        node - the node in question (if null, the function returns null)
        Returns:
        the value of the nilled accessor. Returns null for any node other than an element node. For an element node, returns true if the element has been validated and has an xsi:nil attribute whose value is true.
      • isNilled

        public static boolean isNilled​(NodeInfo node)
        Determine whether a node is nilled. Returns true if the value of the nilled property is true; false if the value is false or absent
      • call

        public SequenceIterator call​(SequenceIterator[] arguments,
                                     XPathContext context)
                              throws XPathException
        Evaluate the expression
        Specified by:
        call in interface CallableExpression
        Parameters:
        arguments - the values of the arguments, supplied as SequenceIterators
        context - the dynamic evaluation context
        Returns:
        the result of the evaluation, in the form of a SequenceIterator
        Throws:
        XPathException - if a dynamic error occurs during the evaluation of the expression
