MultiFact< SIG, ID, Wrapper > Class Template Reference

#include "lib/multifact.hpp"

Description

template<typename SIG, typename ID, template< class > class Wrapper = PassAsIs>
class lib::factory::MultiFact< SIG, ID, Wrapper >

Factory for creating a family of objects by ID.

The actual factory functions are to be installed from the usage site through calls to defineProduction . Each generated object will be treated by the Wrapper template, allowing for the generation of smart-ptrs. The embedded class Singleton allows to build a family of singleton objects; it is to be instantiated at the call site and acts as singleton factory, accessible through a MultiFact instance as frontend.

template<typename... ARGS>

Product operator() ( ID const &  id, ARGS &&...  args  )

inline

Core operation of the factory: Select a production line and invoke the fabrication function.

Parameters

id	select the actual pre installed fabrication function to use
args	additional arguments to pass to the fabrication.

Note

the template parameter SIG defines the raw or nominal signature of the fabrication, and especially the number of arguments

Returns

the created product, after passing through the #Wrapper functor
