Defined in header <stdexcept>
template< class T > class tx_exception : public std::runtime_error;		(TM TS)

Defines an exception type that can be used to cancel and roll back an atomic transaction initiated by the keyword atomic_cancel

If T is not TriviallyCopyable, the program that specializes std::tx_exception<T> is ill-formed.

Member functions

std::tx_exception::tx_exception

explicit tx_exception( T value ) transaction_safe;	(1)
tx_exception( T value, const std::string& what_arg ) transaction_safe;	(2)
tx_exception( T value, const char* what_arg ) transaction_safe;	(3)

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

Parameters

value	-	payload object
what_arg	-	explanatory string

Exceptions

(none)

std::tx_exception::get

T get() const transaction_safe;

Returns the payload object object held by the exception object.

Exceptions

Inherited from std::runtime_error

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)
