makeNewContext

public XPathContext makeNewContext(XPathContext callingContext,
                                   ContextOriginator originator)

Prepare an XPathContext object for evaluating the function

Specified by:

makeNewContext in interface FunctionItem

Overrides:

makeNewContext in class AbstractFunction

Parameters:

callingContext - the XPathContext of the function calling expression

originator - identifies the location of the caller for diagnostics

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

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
