    • Method Detail

      • call

        public Sequence call​(XPathContext context,
                             Sequence[] arguments)
                      throws XPathException
        Evaluate the expression as a general function call
        Parameters:
        context - the dynamic evaluation context
        arguments - the values of the arguments, supplied as SequenceIterators
        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
      • makeFunctionCall

        public Expression makeFunctionCall​(Expression[] arguments)
        Description copied from class: SystemFunction
        Make an expression that either calls this function, or that is equivalent to a call on this function
        Overrides:
        makeFunctionCall in class SystemFunction
        Parameters:
        arguments - the supplied arguments to the function call
        Returns:
        either a function call on this function, or an expression that delivers the same result
      • getStreamerName

        public java.lang.String getStreamerName()
        Description copied from class: SystemFunction
        Get a name that identifies the class that can be used to evaluate this function in streaming mode, that is, supplying one item or event at a time as it is delivered by the parser. Special streaming support is generally available in Saxon-EE for all system functions that take a sequence as their argument.
        Overrides:
        getStreamerName in class SystemFunction
        Returns:
        a name that identifies a class that supports streamed evaluation of this system function, or null if no such class is available. The mapping of names to classes is defined in the Saxon-EE class StreamerMap. In non-streaming Saxon editions (HE and PE) the method always returns null.
