      • getNamespace

        public java.lang.String getNamespace()
        Description copied from class: BuiltInFunctionSet
        Return the namespace URI for the functions local to this function set.
        Overrides:
        getNamespace in class BuiltInFunctionSet

      • getConventionalPrefix

        public java.lang.String getConventionalPrefix()
        Description copied from class: BuiltInFunctionSet
        Return a conventional prefix for use with this namespace, typically the prefix used in the documentation of these functions.
        Overrides:

      • checkSubscript

        public static int checkSubscript​(IntegerValue subscript,
                                         int limit)
                                  throws XPathException
        Check that a number proposed for use as a subscript is greater than zero and less than the maximum subscript allowed by the implementation (2^31-1), returning the value as a Java int
        Parameters:
        subscript - the proposed subscript (one-based)
        limit - the upper limit allowed (usually the size of the array, sometimes arraysize + 1)
        Returns:
        the proposed subscript as an int, if it is in range (still one-based)
        Throws:
        XPathException - if the subscript is 0, negative, or outside the permitted range
