DefaultParamsWritable

trait DefaultParamsWritable extends MLWritable

Helper trait for making simple Params types writable. If a Params class stores all data as org.apache.spark.ml.param.Param values, then extending this trait will provide a default implementation of writing saved instances of the class. This only handles simple org.apache.spark.ml.param.Param types; e.g., it will not handle org.apache.spark.sql.Dataset.
