public interface DefaultParamsWritable
extends MLWritable
Helper trait for making simple Params types writable. If a Params class stores all data as Param values, then extending this trait will provide a default implementation of writing saved instances of the class. This only handles simple Param types; e.g., it will not handleDataset.
