All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, Freezable

public class ModelParameterSchemaV3
extends SchemaV3<Iced,ModelParameterSchemaV3>

An instance of a ModelParameters schema contains the metadata for a single Model build parameter (e.g., K for KMeans). TODO: add a superclass. TODO: refactor this into with FieldMetadataBase.

Method Detail

fillFromImpl

public ModelParameterSchemaV3 fillFromImpl(Iced iced)

Description copied from class: Schema

Fill this Schema from the given implementation object. If a schema doesn't need to adapt any fields if does not need to override this method.

Overrides:

fillFromImpl in class Schema<Iced,ModelParameterSchemaV3>

createImpl

public Iced createImpl()

Description copied from class: Schema

Create an appropriate implementation object and any child objects but does not fill them. The standard purpose of a createImpl without a fillImpl is to be able to get the default values for all the impl's fields.

For objects without children this method does all the required work. For objects with children the subclass will need to override, e.g. by calling super.createImpl() and then calling createImpl() on its children.

Note that impl objects for schemas which override this method don't need to have a default constructor (e.g., a Keyed object constructor can still create and set the Key), but they must not fill any fields which can be filled later from the schema.

TODO: We could handle the common case of children with the same field names here by finding all of our fields that are themselves Schemas.

Overrides:

createImpl in class Schema<Iced,ModelParameterSchemaV3>

writeJSON_impl

public final AutoBuffer writeJSON_impl(AutoBuffer ab)

ModelParameterSchema has its own serializer so that default_value and actual_value get serialized as their native types. Autobuffer assumes all classes that have their own serializers should be serialized as JSON objects, and wraps them in {}, so this can't just be handled by a customer serializer in IcedWrapper.

Parameters:

ab -

Returns:
