Method Detail

getTargetFieldName

public static Optional<String> getTargetFieldName(org.dmg.pmml.DataDictionary dataDictionary,
                                                  org.dmg.pmml.Model model)

Return an Optional with the name of the field whose usageType is TARGET or PREDICTED

While the xsd schema does not strictly enforce this, it seems that by convention majority of models has only one target.

(see https://github.com/jpmml/jpmml-evaluator/issues/64 discussion)

Parameters:

model -

Returns:

getTargetFieldType

public static org.kie.pmml.api.enums.DATA_TYPE getTargetFieldType(org.dmg.pmml.DataDictionary dataDictionary,
                                                                  org.dmg.pmml.Model model)

Return the DATA_TYPE> of the field whose usageType is TARGET or PREDICTED. It throws exception if none of such fields are found

While the xsd schema does not strictly enforce this, it seems that by convention majority of models has only one target.

(see https://github.com/jpmml/jpmml-evaluator/issues/64 discussion)

Parameters:

dataDictionary -

model -

Returns:

Return a List<KiePMMLNameOpType> of target fields

Parameters:

dataDictionary -

model -

Returns:

getTargetFieldsTypeMap
