Method Detail

evaluate

public PerformanceVector evaluate(ExampleSet exampleSet)
                           throws OperatorException

Description copied from class: AbstractExampleSetEvaluator

Implements the evaluation. Called by AbstractExampleSetEvaluator.apply().

Specified by:

evaluate in class AbstractExampleSetEvaluator

Throws:

OperatorException

getInputDescription

public InputDescription getInputDescription(java.lang.Class cls)

Shows a parameter keep_example_set with default value "false".

Overrides:

getInputDescription in class Operator

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
