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.

Member Function Documentation

operator()()

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
