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<decltype(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<decltype(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
