public class AttributeMerge
extends AbstractDataProcessing

This operator merges two attributes by simply concatenating the values and store those new values in a new attribute which will be nominal. If the resulting values are actually numerical, you could simply change the value type afterwards with the corresponding operators.

Method Detail

apply

public ExampleSet apply(ExampleSet exampleSet)
                 throws OperatorException

Description copied from class: AbstractExampleSetProcessing

Delegate for the apply method. In most cases, the returned example set will be the same as the example set or a modified clone.

Specified by:

apply in class AbstractExampleSetProcessing

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
