public class Date2Numerical
extends AbstractDataProcessing

This operator changes a date attribute into a numerical one. It allows to specify exactly which entity should be extracted and to which unit or date it should relate. As an example, it is possible to extract seconds within a minute. Analogously, it is also possible to extract the day within a month. But it is also possible to extract the day within a week or within a year. For all time units, it is also possible to extract the number which has passed by since 1970-01-01 00:00.

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:
