Method Details

format

public String format()

Description copied from interface: MLFormatRegister

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.

Specified by:

format in interface MLFormatRegister

Returns:

(undocumented)

stageName

public String stageName()

Description copied from interface: MLFormatRegister

The string that represents the stage type that this writer supports. This is, along with format, is overridden by children to provide a nice alias for the writer. For example:

   override def stageName(): String =
       "org.apache.spark.ml.regression.LinearRegressionModel"
 

Indicates that this format is capable of saving Spark's own PMML model.

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

Specified by:

stageName in interface MLFormatRegister

Returns:

(undocumented)

write

public void write(String path,
 SparkSession sparkSession,
 scala.collection.mutable.Map<String,String> optionMap,
 PipelineStage stage)

Description copied from interface: MLWriterFormat

Function to write the provided pipeline stage out.

Specified by:

write in interface MLWriterFormat

Parameters:

path - The path to write the result out to.

sparkSession - SparkSession associated with the write request.

optionMap - User provided options stored as strings.

stage - The pipeline stage to be saved.
