NAME
std_function.h
SYNOPSIS
Classes struct std::__is_location_invariant< _Tp > class std::_Function_base Base class of all polymorphic function object wrappers. class std::bad_function_call Exception class thrown when class template function's operator() is called with an empty target. class std::function< _Res(_ArgTypes...)> Polymorphic function wrapper. Namespaces namespace std ISO C++ entities toplevel namespace is std. namespace std::__detail Implementation details not part of the namespace std interface. Enumerations enum _Manager_operation { __get_type_info, __get_functor_ptr, __clone_functor, __destroy_functor } Functions template<typename _Res , typename... _Args> bool std::operator!= (const function< _Res(_Args...)> &__f, nullptr_t) noexcept Compares a polymorphic function object wrapper against 0 (the NULL pointer). template<typename _Res , typename... _Args> bool std::operator!= (nullptr_t, const function< _Res(_Args...)> &__f) noexcept This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. template<typename _Res , typename... _Args> bool std::operator== (const function< _Res(_Args...)> &__f, nullptr_t) noexcept Compares a polymorphic function object wrapper against 0 (the NULL pointer). template<typename _Res , typename... _Args> bool std::operator== (nullptr_t, const function< _Res(_Args...)> &__f) noexcept This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. template<typename _Res , typename... _Args> void std::swap (function< _Res(_Args...)> &__x, function< _Res(_Args...)> &__y) noexcept Swap the targets of two polymorphic function object wrappers.
Detailed Description
This is an internal header file, included by other library headers. Do not attempt to use it directly. Instead, include <functional>.
