std::experi...nges::invoke(3) C++ Standard Libarystd::experi...nges::invoke(3) NAME std::experimental::ranges::invoke - std::experimental::ranges::invoke Synopsis Defined in header <experimental/ranges/functional> template < class F, class... Args > (ranges TS) std::result_of_t<F&&(Args&&...)> invoke(F&& f, Args&&... args); Invoke the Callable object f with the parameters args, and return the result, as if by return INVOKE(std::forward<F>(f), std::forward<Args>(args)...);, where INVOKE(f, t1, t2, ..., tN) is defined as follows: * if f is a pointer to member function of class T: * If std::is_base_of<T, std::decay_t<de- cltype(t1)>>::value is true, then INVOKE(f, t1, t2, ..., tN) is equivalent to (t1.*f)(t2, ..., tN) * otherwise, INVOKE(f, t1, t2, ..., tN) is equivalent to ((*t1).*f)(t2, ..., tN). * otherwise, if N == 1 and f is a pointer to data member of class T: * If std::is_base_of<T, std::decay_t<de- cltype(t1)>>::value is true, then INVOKE(f, t1) is equivalent to t1.*f * otherwise, then INVOKE(f, t1) is equivalent to (*t1).*f * otherwise, INVOKE(f, t1, t2, ..., tN) is equivalent to f(t1, t2, ..., tN) (that is, f is a FunctionObject) Parameters f - Callable object to be invoked args - arguments to pass to f See also invoke invokes any Callable object with given arguments invoke_r and possibility to specify return type (C++17) (since C++23) (C++23) (function template) http://cppreference.com 2022.07.31 std::experi...nges::invoke(3)
