    • Method Detail

      • getIntrinsicDependencies

        public int getIntrinsicDependencies()
        Determine the dependencies
        Overrides:
        getIntrinsicDependencies in class Expression
        Returns:
        a set of bit-significant flags identifying the "intrinsic" dependencies. The flags are documented in class net.sf.saxon.value.StaticProperty
      • iterate

        public SequenceIterator iterate​(XPathContext c)
                                 throws XPathException
        Evaluate the expression
        Overrides:
        iterate in class Expression
        Parameters:
        c - supplies the context for evaluation
        Returns:
        a SequenceIterator that can be used to iterate over the result of the expression
        Throws:
        XPathException - if any dynamic error occurs evaluating the expression
      • 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
