      com.rapidminer.operator.io.AbstractReader<ExampleSet>
          com.rapidminer.operator.io.AbstractExampleSource
              com.rapidminer.operator.io.ExampleSource

All Implemented Interfaces:

ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class AccessExampleSource
extends ExampleSource

This operator can be used to simplify the reading of MS Access databases. Instead of this operator, the operator DatabaseExampleSource can also be used but would have to be properly initialized. This work is performed by this operator so you simply have to specify the basic database file together with the desired table.

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().

Overrides:

createExampleSet in class ExampleSource

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 ExampleSource
