<DL>
<DD>Sets the format of the input instances. If the filter is able to
 determine the output format before seeing any input instances, it
 does so here. This default implementation clears the output format
 and output queue, and the new batch flag is set. Overriders should
 call <code>super.setInputFormat(Instances)</code>
