Template Parameters

Prov	type of provider being set up

The class ProviderSetupClass<Prov> is used by ProviderList to create and set up a new service provider. The class must have a static method setup(), compatible with setupProvider_t signature: it must return a fully set up provider contained in a std::unique_ptr<Prov>.

An example of implementation is DefaultSetupProviderClass, that is in fact the default implementation.

An example to implement a specific setup for a provider, MyProvider:

template <>
struct ProviderSetupClass<MyProvider> {

  static std::unique_ptr<MyProvider> setup
    (MyProvider::Config const& cfg)
    { return std::make_unique<MyProvider>(fhicl::Table<Config>(cfg)); }

}; // ProviderSetupClass<MyProvider>

calling a MyProvider(fhicl::Table<Config> const&) constructor.
