public class MultiRowFinder
extends AbstractTrainableRowFinder

Applies multiple row finding algorithms to the data.
The indices can be either joined or intersected.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to 
    the console (0 = off).
    default: 0
    minimum: 0
 

-finder <adams.data.weka.rowfinder.RowFinder> [-finder ...] (property: finders)
    The row finders to use.
    default: 
 

-combination <JOIN|INTERSECT> (property: combination)
    Defines how the indices are combined.
    default: JOIN
