gko::stop Namespace Reference

The Stopping criterion namespace. More...

Classes
class	Combined
	The Combined class is used to combine multiple criterions together through an OR operation. More...
class	Criterion
	The Criterion class is a base class for all stopping criteria. More...
struct	CriterionArgs
	This struct is used to pass parameters to the EnableDefaultCriterionFactoryCriterionFactory::generate() method. More...
class	Iteration
	The Iteration class is a stopping criterion which stops the iteration process after a preset number of iterations. More...
class	ResidualNormReduction
	The ResidualNormReduction class is a stopping criterion which stops the iteration process when the relative residual norm is below a certain threshold. More...
class	Time
	The Time class is a stopping criterion which stops the iteration process after a certain amout of time has passed. More...

Typedefs
using	CriterionFactory = AbstractFactory< Criterion, CriterionArgs >
	Declares an Abstract Factory specialized for Criterions.
template<typename ConcreteFactory , typename ConcreteCriterion , typename ParametersType , typename PolymorphicBase = CriterionFactory>
using	EnableDefaultCriterionFactory = EnableDefaultFactory< ConcreteFactory, ConcreteCriterion, ParametersType, PolymorphicBase >
	This is an alias for the EnableDefaultFactory mixin, which correctly sets the template parameters to enable a subclass of CriterionFactory. More...

Functions
template<typename FactoryContainer >
std::shared_ptr< const CriterionFactory >	combine (FactoryContainer &&factories)
	Combines multiple criterion factories into a single combined criterion factory. More...

Typedef Documentation

EnableDefaultCriterionFactory

template<typename ConcreteFactory , typename ConcreteCriterion , typename ParametersType , typename PolymorphicBase = CriterionFactory>

using gko::stop::EnableDefaultCriterionFactory = typedef EnableDefaultFactory<ConcreteFactory, ConcreteCriterion, ParametersType, PolymorphicBase>

This is an alias for the EnableDefaultFactory mixin, which correctly sets the template parameters to enable a subclass of CriterionFactory.

Template Parameters

ConcreteFactory	the concrete factory which is being implemented [CRTP parmeter]
ConcreteCriterion	the concrete Criterion type which this factory produces, needs to have a constructor which takes a const ConcreteFactory *, and a const CriterionArgs * as parameters.
ParametersType	a subclass of enable_parameters_type template which defines all of the parameters of the factory
PolymorphicBase	parent of ConcreteFactory in the polymorphic hierarchy, has to be a subclass of CriterionFactory
