  - ### Method Detail

    - #### listOptions

          public java.util.Enumeration<Option> listOptions()

      Returns an enumeration describing the available options.
      Specified by:
        `listOptions` in interface `OptionHandler`
      Overrides:
        `listOptions` in class `ParallelMultipleClassifiersCombiner`
      Returns:
        an enumeration of all the available options.

    - #### setOptions

          public void setOptions(java.lang.String[] options)
                          throws java.lang.Exception

      Parses a given list of options. Valid options are:

      -B classifierstring
      Classifierstring should contain the full class name of a scheme included for selection followed by options to the classifier (required, option should be used once for each classifier).

      -S num
      Set the random number seed (default 1).

      Specified by:
        `setOptions` in interface `OptionHandler`
      Overrides:
        `setOptions` in class `ParallelMultipleClassifiersCombiner`
      Parameters:
        `options` - the list of options as an array of strings
      Throws:
        `java.lang.Exception` - if an option is not supported

    - #### getOptions

          public java.lang.String[] getOptions()

      Gets the current settings of the classifier.
      Specified by:
        `getOptions` in interface `OptionHandler`
      Overrides:
        `getOptions` in class `ParallelMultipleClassifiersCombiner`
      Returns:
        an array of strings suitable for passing to setOptions

    - #### seedTipText

          public java.lang.String seedTipText()

      Returns the tip text for this property
      Returns:
        tip text for this property suitable for displaying in the explorer/experimenter gui

    - #### setSeed

          public void setSeed(int seed)

      Set the seed for random number generation.
      Specified by:
        `setSeed` in interface `Randomizable`
      Parameters:
        `seed` - the seed

    - #### getSeed

          public int getSeed()

      Gets the seed for the random number generations
      Specified by:
        `getSeed` in interface `Randomizable`
      Returns:
        the seed for the random number generation
