        call in interface Callable
        Parameters:
        context - the dynamic evaluation context
        arguments - the values of the arguments, supplied as SequenceIterators
        Returns:

      • 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
        Returns:
        the properties
