public class PartitionedMultiFilter
extends SimpleBatchFilter

A filter that applies filters on subsets of attributes and assembles the output into a new dataset. Attributes that are not covered by any of the ranges can be either retained or removed from the output.

Valid options are:

 -D
  Turns on output of debugging information.

 -F <classname [options]>
  A filter to apply (can be specified multiple times).

 -R <range>
  An attribute range (can be specified multiple times).
  For each filter a range must be supplied. 'first' and 'last'
  are valid indices. 'inv(...)' around the range denotes an
  inverted range.

 -U
  Flag for leaving unused attributes out of the output, by default
  these are included in the filter output.
