All Implemented Interfaces:

java.io.Serializable, OptionHandler

public class Null
extends AbstractOutput

Suppresses all output.

Valid options are:

 -p <range>
  The range of attributes to print in addition to the classification.
  (default: none)

 -distribution
  Whether to turn on the output of the class distribution.
  Only for nominal class attributes.
  (default: off)

 -decimals <num>
  The number of digits after the decimal point.
  (default: 3)

 -file <path>
  The file to store the output in, instead of outputting it on stdout.
  Gets ignored if the supplied path is a directory.

  In case the data gets stored in a file, then this flag can be used
  to suppress the regular output.
  (default: not suppressed)
