-
makeFunctionCall
Make an expression that either calls this function, or that is equivalent to a call on this function- Overrides:
makeFunctionCall
in classRegexFunction
- Parameters:
arguments
- the supplied arguments to the function call- Returns:
- either a function call on this function, or an expression that delivers the same result
-
call
Evaluate the expression- Parameters:
context
- the dynamic evaluation contextarguments
- the values of the arguments, supplied as SequenceIterators- Returns:
- the result of the evaluation, in the form of a SequenceIterator
- Throws:
XPathException
- if a dynamic error occurs during the evaluation of the expression
-
checkReplacement
Check the contents of the replacement string- Parameters:
rep
- the replacement string- Returns:
- null if the string is OK, or an error message if not
