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

std
ISO C++ entities toplevel namespace is std.
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.
