allowRegexMatchingEmptyString
protected boolean allowRegexMatchingEmptyString()- Specified by:
allowRegexMatchingEmptyString
in classRegexFunction
-
evalMatches
public boolean evalMatches(UnicodeString input, UnicodeString regex, UnicodeString flags, XPathContext context) throws XPathException - Throws:
XPathException
-
call
Evaluate the expression- Parameters:
context
- the dynamic evaluation contextarguments
- the values of the arguments, supplied as Sequences- Returns:
- the result of the evaluation, in the form of a Sequence
- Throws:
XPathException
- if a dynamic error occurs during the evaluation of the expression
-
getElaborator

getElaborator
in classSystemFunction
- Returns:
- a suitable elaborator; or null if no custom elaborator is available
