      • getSpecialProperties

        public int getSpecialProperties​(Expression[] arguments)
        Determine the special properties of this function. The general rule is that a system function call is non-creative if its return type is atomic, or if all its arguments are non-creative. This is overridden for the generate-id() function, which is considered creative if its operand is creative (because the result depends on the identity of the operand)

        arguments - the actual arguments to the function call
        the properties
      • bindContext

        public FunctionItem bindContext​(XPathContext context)
        Description copied from class: ContextAccessorFunction
        Bind context information to appear as part of the function's closure. If this method has been called, the supplied context will be used in preference to the context at the point where the function is actually called.
        Specified by:
        bindContext in class ContextAccessorFunction
        context - the context to which the function applies. Must not be null.
      • call

        public Sequence call​(XPathContext context,
                             Sequence[] arguments)
                      throws XPathException
        Call the Callable.
        Specified by:
        call in interface Callable
        call in class ContextAccessorFunction
        context - the dynamic evaluation context
        arguments - the values of the arguments, supplied as Sequences.

        Generally it is advisable, if calling iterate() to process a supplied sequence, to call it only once; if the value is required more than once, it should first be converted to a GroundedValue by calling the utility methd SequenceTool.toGroundedValue().

        If the expected value is a single item, the item should be obtained by calling Sequence.head(): it cannot be assumed that the item will be passed as an instance of Item or AtomicValue.

        It is the caller's responsibility to perform any type conversions required to convert arguments to the type expected by the callee. An exception is where this Callable is explicitly an argument-converting wrapper around the original Callable.

        the result of the evaluation, in the form of a Sequence. It is the responsibility of the callee to ensure that the type of result conforms to the expected result type.
        XPathException - if a dynamic error occurs during the evaluation of the expression
