Class PartitionedMultiFilter

All Implemented Interfaces:
  java.io.Serializable, CapabilitiesHandler, OptionHandler, RevisionHandler

    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.
