Method Detail

modifyMetaData

protected MetaData modifyMetaData(ExampleSetMetaData metaData)
                           throws UndefinedParameterError

Description copied from class: AbstractExampleSetProcessing

Subclasses might override this method to define the meta data transformation performed by this operator.

Overrides:

modifyMetaData in class AbstractExampleSetProcessing

Throws:

UndefinedParameterError

apply

public ExampleSet apply(ExampleSet exampleSet)
                 throws OperatorException

Description copied from class: AbstractExampleSetProcessing

Delegate for the apply method. The given ExampleSet is already a clone of the input example set so that changing this examples set does not affect the original one. Subclasses should avoid cloning again unnecessarily.

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. ATTENTION! This will create new parameterTypes. For calling already existing parameter types use getParameters().getParameterTypes();

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class Operator

writesIntoExistingData

public boolean writesIntoExistingData()

Description copied from class: AbstractExampleSetProcessing

This method indicates whether the operator will perform a write operation on a cell in an existing column of the example set's ExampleTable. If yes, the original example will be completely copied in memory if the original port is used.

Specified by:

writesIntoExistingData in class AbstractExampleSetProcessing

getResourceConsumptionEstimator

public ResourceConsumptionEstimator getResourceConsumptionEstimator()

Description copied from class: Operator

Subclasses can override this method if they are able to estimate the consumed resources (CPU time and memory), based on their input. The default implementation returns null.

Specified by:

getResourceConsumptionEstimator in interface ResourceConsumer

Overrides:

getResourceConsumptionEstimator in class Operator
