A question about MultipleOutputFormat

Hello,
MultipleOutputFormat is a very good idea. Thanks. I have a question,
from the web page ,
"The reducer wants to write data to different files depending on the
actual keys" .. and values.
Examining, TestMultipleTextOutputFormat,

class KeyBasedMultipleTextOutputFormat extends
MultipleTextOutputFormat<Text, Text>

In my implementation, will the key and value classes be the same as
the ones given to the Reduce? or the Map?

Thank you
Saptarshi
