Method Detail

setValue

protected abstract void setValue(Example example,
                                 Attribute newAttribute,
                                 double value)
                          throws OperatorException

Throws:

OperatorException

getGeneratedAttributevalueType

protected abstract int getGeneratedAttributevalueType()

Returns Ontology.NOMINAL or one of its subtypes.

makeAttribute

protected Attribute makeAttribute()

init

public void init()
          throws OperatorException

Will be invoked before the setValue method is invoked for each example. This default implementation does nothing.

Throws:

OperatorException

cleanUp

public void cleanUp()
             throws OperatorException

Will be invoked after the setValue method was invoked for each example. This default implementation does nothing.

Throws:

OperatorException

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
