Defined in header <optional>
class bad_optional_access;		(library fundamentals TS)

Defines a type of object to be thrown as exception when accessing a std::experimental::optional object with uninitialized state.

Inheritance diagram

Member functions

(constructor)

constructs the exception object (public member function)

std::bad_optional_access::bad_optional_access

explicit bad_optional_access( const std::string& what_arg );	(1)	(library fundamentals TS)
explicit bad_optional_access( const char* what_arg );	(2)	(library fundamentals TS)

Constructs the exception object with what_arg as explanatory string that can be accessed through what().

Parameters

what_arg

-

explanatory string

Exceptions

(none)

Inherited from std::exception

Member functions

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