Detailed Description

template<bool many, typename Base, typename... Args>
class ezconfig::GeneralFactory< many, Base, Args >

A Factory creates objects in a class hierarchy.

Template Parameters

many	whether to create a one-to-many factory or a one-to-one factory.
Signature	type signature Base(Args...) where Base is the hierarchy base class, and Args... are the inputs to the factory methods.

If many = false, then the factory is (Args...) -> std::unique_ptr<Base> If many = true, then the factory is (Args...) -> std::vector<std::unique_ptr<Base>>
