DependencyFactory< OBJ > Class Template Reference

#include "lib/depend.hpp"

Description

template<class OBJ>
class lib::DependencyFactory< OBJ >

Helper to abstract creation and lifecycle of a dependency.

Holds a configurable constructor function and optionally an automatically invoked deleter function.

Note

DependencyFactory can be declared friend to indicate the expected way to invoke an otherwise private ctor. This is a classical idiom for singletons.
