Defines a type of object to be thrown by std::experimental::optional::value when accessing an optional object that does not contain a value.

Inheritance diagram

Member functions

(constructor)

constructs the exception object (public member function)

Inherited from std::exception

Member functions

(destructor) [virtual]	destroys the exception object (virtual public member function of std::exception)
what [virtual]	returns an explanatory string (virtual public member function of std::exception)
