columnToAppended - mapping of existing column names to binned column names that are appended

mapper - mapping data column names to PMML derived field names and vice versa

Method Detail

exportToTransDict

public org.dmg.pmml40.TransformationDictionaryDocument.TransformationDictionary exportToTransDict()

Exports the translators state to a new TransformationDictionary element.

Specified by:

exportToTransDict in interface PMMLPreprocTranslator

Returns:

the transformation dictionary containing the preprocessing elements

exportToLocalTrans

public org.dmg.pmml40.LocalTransformationsDocument.LocalTransformations exportToLocalTrans()

Exports the translators state to a new LocalTransformations element.

Specified by:

exportToLocalTrans in interface PMMLPreprocTranslator

Returns:

the local transformations containing the preprocessing elements

initializeFrom

public List<Integer> initializeFrom(org.dmg.pmml40.DerivedFieldDocument.DerivedField[] derivedFields)

Initializes the translator based on a derived field array.

Specified by:

initializeFrom in interface PMMLPreprocTranslator

Parameters:

derivedFields - the derived fields to initialize from

Returns:

a list with the indices of all derived field entries that could be consumed
