What is the meaning of not specifying a template parameter?

[JUANDENT]

Hi,

I found this code which I don't understand:

using namespace boost;
  auto injector = di::make_injector(
    di::bind<ILogger>().to<ConsoleLogger>(),
	  di::bind<>().named(some_name).to(4.5f),
	  di::bind<>().named(int_name).to(5)
  );

How come di::bind is used with no template parameter? What does that mean and what is the difference between di::bind<> and di::bind<ILogger>?

Regards,

Juan

I believe di::bind is a template struct and di::bind<ILogger>() creates an object of type di::bind<ILogger>.
