to select or filter on the provider class without instantiating the
provider.

type
public abstract Class<? extends S> type ()
Returns the provider type. There is no guarantee that this type is
accessible or that it has a public no-args constructor. The get() method should be used to obtain the provider instance.
When a module declares that the provider class is created by a
provider factory then this method returns the return type of its
public static "provider()" method.
