- ## Method Details

  - ### listOptions

    public 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(String[] options) throws 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:
      `Exception` - if an option is not supported

  - ### getOptions

    public 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 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
