public class ChangeAttributeNamesReplace
extends AbstractDataProcessing

This operator replaces parts of the attribute names (like whitespaces, parentheses, or other unwanted characters) by a specified replacement. The replace_what parameter can be defined as a regular expression (please refer to the annex of the RapidMiner tutorial for a description). The replace_by parameter can be defined as an arbitrary string. Empty strings are also allowed. Capturing groups of the defined regular expression can be accessed with $1, $2, $3...

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
