Execute an XPath function object.
The function must return a valid object. Called if function has two parameters.
executionContext | executing context |
context | current context node |
arg1 | pointer to XObject argument |
arg2 | pointer to XObject argument |
locator | LocatorType instance for the XPath expression that contains the function call |
Reimplemented from Function.
virtual const XalanDOMString& FunctionSubstringBefore::getError | ( | XalanDOMString & | theBuffer | ) | const [protected, virtual] |
Get the error message to report when the function is called with the wrong number of arguments.
Implements Function.
