In case the output format cannot be returned immediately, i.e., hasImmediateOutputFormat() returns false, then this method will called from batchFinished() after the call of preprocess(Instances), in which, e.g., statistics for the actual processing step can be gathered.
        Specified by:
        determineOutputFormat in class weka.filters.SimpleStreamFilter
        Parameters:
        inputFormat - the input format to base the output format on
