Defines

HPX_INVOKE_R(R, F, ...)
namespace hpx
namespace util

Functions

template<typename F, typename ...Ts>
constexpr util::invoke_result<F, Ts...>::type 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.

template<typename R, typename F, typename ...Ts>
constexpr R invoke_r(F &&f, Ts&&... vs)

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