Interface MLFormatRegister

All Superinterfaces:
MLWriterFormat
All Known Implementing Classes:
InternalKMeansModelWriter, InternalLinearRegressionModelWriter, PMMLKMeansModelWriter, PMMLLinearRegressionModelWriter

public interface MLFormatRegister extends MLWriterFormat
ML export formats for should implement this trait so that users can specify a shortname rather than the fully qualified class name of the exporter.

A new instance of this class will be instantiated each time a save call is made.

  • Method Details

    • format

      String format()
      The string that represents the format that this format provider uses. This is, along with stageName, is overridden by children to provide a nice alias for the writer. For example:

      
         override def format(): String =
             "pmml"
       
      Indicates that this format is capable of saving a pmml model.

      Must have a valid zero argument constructor which will be called to instantiate.

      Format discovery is done using a ServiceLoader so make sure to list your format in META-INF/services.

      Returns:

             "org.apache.spark.ml.regression.LinearRegressionModel"
       
      Indicates that this format is capable of saving Spark's own PMML model.
