Functions

template<typename F, typename Tuple>constexpr HPX_HOST_DEVICE detail::invoke_fused_result<F, Tuple>::type hpx::util::invoke_fused(F && f, Tuple && t)

Invokes the given callable object f with the content of the sequenced type t (tuples, pairs)

Return

The result of the callable object when it’s called with the content of the given sequenced type.

Note

This function is similar to std::apply (C++17)

Parameters
  • f: Must be a callable object. If f is a member function pointer, the first argument in the sequenced type will be treated as the callee (this object).

  • t: A type which is content accessible through a call to hpx::util::get.

Exceptions
  • std::exception: like objects thrown by call to object f with the arguments contained in the sequenceable type t.

template<typename R, typename F, typename Tuple>constexpr HPX_HOST_DEVICE R hpx::util::invoke_fused_r(F && f, Tuple && t)

Template Parameters
  • R: The result type of the function when it’s called with the content of the given sequenced type.

template<typename F, typename... Ts>constexpr HPX_HOST_DEVICE util::invoke_result<F, Ts...>::type hpx::util::invoke(F && f, Ts &&... vs)

Invokes the given callable object f with the content of the argument pack vs

Return

The result of the callable object when it’s called with the given argument types.

Note

This function is similar to std::invoke (C++17)

Parameters
  • f: Requires to be a callable object. If f is a member function pointer, the first argument in the pack will be treated as the callee (this object).

  • vs: An arbitrary pack of arguments

Exceptions
  • std::exception: like objects thrown by call to object f with the argument types vs.
