      • getParseOptions

        public ParseOptions getParseOptions()
        Get the parsing options set via setParseOptions()
        Returns:
        the parsing options
      • setParseOptions

        public void setParseOptions​(ParseOptions parseOptions)
        Set options to be used for the parsing operation. Defaults to the parsing options set in the Configuration
        Parameters:
        parseOptions - the parsing options to be used. Currently only affects the behaviour of the sendDocument() method (used in streamed merging)
      • getCardinality

        public int getCardinality​(Expression[] arguments)
        Description copied from class: SystemFunction
        Get the cardinality, given knowledge of the actual arguments
        Overrides:
        getCardinality in class SystemFunction
        Parameters:
        arguments - the actual arguments supplied
        Returns:
        the most precise available cardinality that the function will return
      • 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
      • call

        public ZeroOrOne call​(XPathContext context,
                              Sequence[] arguments)
                       throws XPathException
        Evaluate the expression
        Specified by:
        call in interface Callable
        Specified by:
        call in interface Function
        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
      • getSpecialProperties

        public int getSpecialProperties​(Expression[] arguments)
        Get the static properties of this expression (other than its type). The result is bit-signficant. These properties are used for optimizations. In general, if property bit is set, it is true, but if it is unset, the value is unknown.
        Overrides:
        getSpecialProperties in class SystemFunction
        Parameters:
        arguments - the expressions supplied as arguments to the function
