Method Detail

validateAndTransformSchema

StructType validateAndTransformSchema(StructType schema,
                                    ParamMap paramMap,
                                    boolean fitting,
                                    DataType featuresDataType)

Description copied from interface: PredictorParams

Validates and transforms the input schema with the provided param map.

Specified by:

validateAndTransformSchema in interface PredictorParams

Parameters:

schema - input schema

paramMap - additional parameters

fitting - whether this is in fitting

featuresDataType - SQL DataType for FeaturesType. E.g., VectorUDT for vector features.

Returns:

output schema
