UDTF with optional parameter

Hi,

Is it possible to write a UDTF with an optional parameter? I was  
intending to write a function that works like explode, but can provide  
extended functionality given an optional integer flag set to 1. Since  
GenericUDTF's initialize function only uses ObjectInspector[] I  
currently don't see how to inspect the actual value (not just the  
type) of an input parameter.

Thanks for your help,
Niko
