Add noexcept to conform with C++11
I'm adding BOOST_NOEXCEPT specification to Boost.Thread (#7279), and I can not complete it as Boost.System lacks this feature.
class error_category {
public:
virtual const char* name() const noexcept = 0;
virtual error_condition default_error_condition(int ev) const noexcept;
virtual bool equivalent(int code, const error_condition& condition) const noexcept;
virtual bool equivalent(const error_code& code, int condition) const noexcept;
bool operator==(const error_category& rhs) const noexcept;
bool operator!=(const error_category& rhs) const noexcept;
bool operator<(const error_category& rhs) const noexcept;
};
const error_category& generic_category() noexcept;
const error_category& system_category() noexcept;
class error_code {
public:
error_code() noexcept;
error_code(int val, const error_category& cat) noexcept;
template <class ErrorCodeEnum>
error_code(ErrorCodeEnum e) noexcept;
void assign(int val, const error_category& cat) noexcept;
template <class ErrorCodeEnum>
errorcode& operator=(ErrorCodeEnum e) noexcept;
void clear() noexcept;
int value() const noexcept;
const error_category& category() const noexcept;
error_condition default_error_condition() const noexcept;
explicit operator bool() const noexcept;
};
error_code make_error_code(errc e) noexcept;
bool operator<(const error_code& lhs, const error_code& rhs) noexcept;
class error_condition {
public:
error_condition() noexcept;
error_condition(int val, const error_category& cat) noexcept;
template <class ErrorConditionEnum>
error_condition(ErrorConditionEnum e) noexcept;
void assign(int val, const error_category& cat) noexcept;
template<class ErrorConditionEnum>
error_condition& operator=(ErrorConditionEnum e) noexcept;
void clear() noexcept;
int value() const noexcept;
const error_category& category() const noexcept;
explicit operator bool() const noexcept;
};
bool operator<(const error_condition& lhs, const error_condition& rhs) noexcept;
Any plans to take care of this?
