Class GridSearchHandler<G extends Grid<MP>,S extends GridSearchSchema<G,S,MP,P>,MP extends Model.Parameters,P extends ModelParametersSchemaV3>

java.lang.Object

jsr166y.ForkJoinTask<java.lang.Void>

jsr166y.CountedCompleter

water.H2O.H2OCountedCompleter<Handler>

water.api.Handler

water.api.GridSearchHandler<G,S,MP,P>

Type Parameters:

G - Implementation output of grid search

MP - Type of model parameters

P - Type of schema representing model parameters

S - Schema representing structure of grid search end-point

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.concurrent.Future<java.lang.Void>, Freezable<Handler>

public class GridSearchHandler<G extends Grid<MP>,S extends GridSearchSchema<G,S,MP,P>,MP extends Model.Parameters,P extends ModelParametersSchemaV3>
extends Handler

A generic grid search handler implementing launch of grid search.

A model specific grid search handlers should inherit from class and implements corresponding methods. FIXME: how to get rid of P, since it is already enforced by S
