class UDFTransformer extends Transformer with Wrappable with ComplexParamsWritable with HasInputCol with HasInputCols with HasOutputCol with BasicLogging

UDFTransformer takes as input input column, output column, and a UserDefinedFunction returns a dataframe comprised of the original columns with the output column as the result of the udf applied to the input column
