Detailed Description

template<typename AbstractProductType, typename ComponentsType>
class gko::AbstractFactory< AbstractProductType, ComponentsType >

The AbstractFactory is a generic interface template that enables easy implementation of the abstract factory design pattern.

The interface provides the AbstractFactory::generate() method that can produce products of type AbstractProductType using an object of ComponentsType (which can be constructed on the fly from parameters to its constructors). The generate() method is not declared as virtual, as this allows subclasses to hide the method with a variant that preserves the compile-time type of the objects. Instead, implementers should override the generate_impl() method, which is declared virtual.

Implementers of concrete factories should consider using the EnableDefaultFactory mixin to obtain default implementations of utility methods of PolymorphicObject and AbstractFactory.

Template Parameters
AbstractProductTypethe type of products the factory produces
ComponentsTypethe type of components the factory needs to produce the product

Member Function Documentation

◆ generate()

template<typename AbstractProductType, typename ComponentsType>
template<typename... Args>
std::unique_ptr<abstract_product_type> gko::AbstractFactory< AbstractProductType, ComponentsType >::generate ( Args &&...  args) const
inline

Creates a new product from the given components.

The method will create an ComponentsType object from the arguments of this method, and pass it to the generate_impl() function which will create a new AbstractProductType.

Template Parameters
Argstypes of arguments passed to the constructor of ComponentsType
Parameters
argsarguments passed to the constructor of ComponentsType
Returns
an instance of AbstractProductType
