    public class WekaDataGenerator
extends AbstractSimpleSourceWithPropertiesUpdating
    Generates artificial data using a Weka data generator.

    Input/output:
    - generates:
       weka.core.Instances


    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)

    -stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow execution at this level gets stopped in case this
    actor encounters an error; the error gets propagated; useful for critical
    actors.
    default: false
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing

    The names of the variables to update the properties with.
    default:
 
    -generator <weka.datagenerators.DataGenerator> (property: dataGenerator)
    The data generator to use for generating the weka.core.Instances object.
    default: weka.datagenerators.classifiers.classification.Agrawal -r weka.datagenerators.classifiers.classification.Agrawal-S_1_-n_100_-F_1_-P_0.05 -S 1 -n 100 -F 1 -P 0.05
