Typedef Documentation

using Acts::Concepts::is_detected = typename detail::detector<detail::nonesuch, void, Op, Args...>::value_t

This type ties together the detection idiom.

It instantiates the detector template with the Op and Args and resolves to the exact value type. In essence, if Op<Args...> succeeds, this will evaluate to std::true_type, and if not, it will evaluate to std::false_type.

Template Parameters

• Op: The operation to test

• Args: The arguments to the operation
