All Implemented Interfaces:

Callable, Function, GroundedValue, Item, Sequence

public class LoadXqueryModule
extends SystemFunction
implements Callable

This class implements the function load-xquery-module(), which is a standard function in XPath 3.1. It is classified as a higher-order function and therefore requires Saxon-PE or higher.

makeNewContext

public XPathContext makeNewContext(XPathContext callingContext,
                                   ContextOriginator originator)

Prepare an XPathContext object for evaluating the function

Specified by:

makeNewContext in interface Function

Overrides:

makeNewContext in class AbstractFunction

Parameters:

callingContext - the XPathContext of the function calling expression

originator -

Returns:

a suitable context for evaluating the function (which may or may not be the same as the caller's context)

call

public MapItem call(XPathContext context,
                    Sequence[] args)
             throws XPathException

Invoke the function

Specified by:

call in interface Callable

Specified by:

call in interface Function

Parameters:

context - the XPath dynamic evaluation context

args - the actual arguments to be supplied

Returns:

the result of invoking the function

Throws:

XPathException - if a dynamic error occurs within the function
