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
