class MyTransformer extends UnaryTransformer[Double, Double, MyTransformer] with DefaultParamsWritable

Simple Transformer which adds a constant value to input Doubles.

UnaryTransformer can be used to create a stage usable within Pipelines. It defines parameters for specifying input and output columns: UnaryTransformer.inputCol and UnaryTransformer.outputCol. It can optionally handle schema validation.

DefaultParamsWritable provides a default implementation for persisting instances of this Transformer.
