GetFunctionArgumentTypesPlain

template<typename Function>

using ProcessLib::Graph::detail::GetFunctionArgumentTypesPlain

Initial value:

        std::remove_cvref_t,
        typename GetFunctionArgumentTypes<Function>::type>>

Function Documentation

applyImpl()

template<typename Function, typename... Args>

auto ProcessLib::Graph::detail::applyImpl	(	Function &&	f,
		Args &&...	args ) -> typename detail::GetFunctionReturnType<std::decay_t<Function>>::type

Invokes the passed function f.

f can be a function object, a free function, or a member function pointer. In the latter case, the first entry of args must be the object for which f shall be invoked. (The remainder of) args are an arbitrary number of tuples from which arguments to f are taken based on their types.
