    public abstract class ClusterGenerator

extends DataGenerator

Abstract class for cluster data generators.

Example usage as the main of a datagenerator called RandomGenerator:

     public static void main(String[] args) {
       try {
         DataGenerator.makeData(new RandomGenerator(), args);
       }
       catch (Exception e) {
         e.printStackTrace();
         System.err.println(e.getMessage());
       }
     }

Constructor Detail

### ClusterGenerator

    public ClusterGenerator()

  initializes the generator

Method Detail

### listOptions

    public java.util.Enumeration listOptions()

  Returns an enumeration describing the available options.

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

### setOptions

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

  Sets the options.

  Specified by:
    `setOptions` in interface `OptionHandler`
  Overrides:
    `setOptions` in class `DataGenerator`
  Parameters:
    `options` - the options
  Throws:
    `java.lang.Exception` - if invalid option

### getOptions

    public java.lang.String[] getOptions()

  Gets the current settings of the classifier.

  Specified by:
    `getOptions` in interface `OptionHandler`
  Overrides:
    `getOptions` in class `DataGenerator`
  Returns:
    an array of strings suitable for passing to setOptions
  See Also:
    `DataGenerator.removeBlacklist(String[])`

### setNumAttributes

    public void setNumAttributes(int numAttributes)

  Sets the number of attributes the dataset should have.

  Parameters:
    `numAttributes` - the new number of attributes

### getNumAttributes

    public int getNumAttributes()

  Gets the number of attributes that should be produced.

  Returns:
    the number of attributes that should be produced

### numAttributesTipText

    public java.lang.String numAttributesTipText()

  Returns the tip text for this property

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

### setClassFlag

    public void setClassFlag(boolean classFlag)

  Sets the class flag, if class flag is set, the cluster is listed as class atrribute in an extra attribute.

  Parameters:
