Detailed Description

template<typename FactoryType>
class gko::deferred_factory_parameter< FactoryType >

Represents a factory parameter of factory type that can either initialized by a pre-existing factory or by passing in a factory_parameters object whose .on(exec) will be called to instantiate a factory.

Template Parameters

FactoryType

the type of factory that can be instantiated from this object.

Constructor & Destructor Documentation

deferred_factory_parameter()

template<typename FactoryType>

template<typename ParametersType , typename U = decltype(std::declval<ParametersType>().on( std::shared_ptr<const Executor>{})), std::enable_if_t< detail::is_pointer_convertible< typename U::element_type, FactoryType >::value > * = nullptr>

gko::deferred_factory_parameter< FactoryType >::deferred_factory_parameter ( ParametersType  parameters )

inline

Creates a deferred factory parameter object from a factory_parameters-like object.

To instantiate the actual factory, the parameter's .on(exec) function will be called.

Member Function Documentation

on()

template<typename FactoryType>

std::shared_ptr<FactoryType> gko::deferred_factory_parameter< FactoryType >::on ( std::shared_ptr< const Executor >  exec ) const

inline

Instantiates the deferred parameter into an actual factory.

This will throw if the deferred factory parameter is empty.
