All Implemented Interfaces:

ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class MassiveDataGenerator
extends AbstractExampleSource

Generates huge amounts of data in either sparse or dense format. This operator can be used to check if huge amounts of data can be handled by RapidMiner for a given process setup without creating the correct format / writing special purpose input operators.

Method Detail

createExampleSet

public ExampleSet createExampleSet()
                            throws OperatorException

Description copied from class: AbstractExampleSource

Creates (or reads) the ExampleSet that will be returned by AbstractReader.apply().

Specified by:

createExampleSet in class AbstractExampleSource

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class Operator
