Adding user defined functions
Hello,
I have an Excel addin that contains a few functions written in C. In addition,
I have the equivalent set of functions written in Java.
How can I "register" the equivalent functions so that they get recognised by
the FormulaEvaluator in hssf?
(I have read the "Eval Dev Guide", but I suspect I may have to add entires to
the functionMetadata.txt file)
Many thanks,
Dan

Dave,
Many thanks for the quick response.
The timeline for this part is probably a few weeks.
Do you know if anyone has done any work on this? I'd be happy to get involved.
Regards,
Dan

Hi,
This functionality is not yet in POI - it has been requested with some
frequency. Please join the dev list. We would certainly discuss how to
add a registration api to HSSF/XSSF for UDFs. Contributions are welcome.
What is the timeline for your project?
Regards,
Dave
