Description copied from class: EvalFunc

Since the dataset may be divided up in a variety of ways the programmer should not make assumptions about state that is maintained between invocations of this method.

Specified by:
exec in class EvalFunc<org.joda.time.DateTime>
input - the Tuple to be processed.
result, of type T.
