      • makeOptimizedFunctionCall

                                                    ContextItemStaticInfo contextInfo,
                                                    Expression... arguments)
                                             throws XPathException
        Allow the function to create an optimized call based on the values of the actual arguments
        makeOptimizedFunctionCall in class SystemFunction
        visitor - the expression visitor
        contextInfo - information about the context item
        arguments - the supplied arguments to the function call. Note: modifying the contents of this array should not be attempted, it is likely to have no effect.
        either a function call on this function, or an expression that delivers the same result, or null indicating that no optimization has taken place
        XPathException - if an error is detected
      • call

        public StringValue call​(XPathContext context,
                                Sequence[] arguments)
                         throws XPathException
        Evaluate the function call
        Specified by:
        call in interface Callable
        context - the dynamic evaluation context
        arguments - the values of the arguments, supplied as SequenceIterators
        the result of the evaluation, in the form of a SequenceIterator
        XPathException - if a dynamic error occurs during the evaluation of the expression
      • yesOrNo

        public static java.lang.String yesOrNo​(boolean whatever)
      • getProperty

        public static java.lang.String getProperty​(java.lang.String uri,

        Here's the real code:
        uri - the namespace URI of the system property name
        local - the local part of the system property name
        rsc - context information
        the value of the corresponding system property
