In c++, what does the using Signature line do? I really dont get it, what is Signature?

class XX { 
public:
    using Signature = void(std::stringstream&&);    
}

Signature is further used once like this:

using Function = std::function<Signature>;

It is modern alternative to `typedef` – Slava Oct 11 '17 at 14:50

`Signature` is a [type alias](http://en.cppreference.com/w/cpp/language/type_alias) of a function that takes `std::stringstream&&` as parameter and returns `void`. – AMA Oct 11 '17 at 14:52
Thanks a lot, I really did not see this... – Patrick Liedtke Oct 11 '17 at 15:08
