std::tx_exception(3) C++ Standard Libary std::tx_exception(3) NAME std::tx_exception - std::tx_exception Synopsis Defined in header <stdexcept> template< class T > (TM TS) class tx_exception : public std::runtime_error; 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_ex- ception<T> is ill-formed. Member functions std::tx_exception::tx_exception explicit tx_exception( T value ) transaction_safe; (1) (TM TS) tx_exception( T value, const std::string& what_arg ) transaction_safe; (2) (TM TS) tx_exception( T value, const char* what_arg ) transaction_safe; (3) (TM TS) tx_exception( const tx_exception& other ) transaction_safe noexcept; (4) (TM TS) 1-3) 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(). 4) Copy constructor. If *this and other both have dynamic type std::tx_exception<T> then std::strcmp(what(), other.what()) == 0. Parameters value - payload object what_arg - explanatory string other - another exception object to copy Exceptions 1-3) May throw implementation-defined exceptions. std::tx_exception::operator= tx_exception& operator=( const tx_exception& other ) transaction_safe (TM TS) noexcept; Assigns the contents with those of other. If *this and other both have dynamic type std::tx_exception<T> then std::strcmp(what(), other.what()) == 0 after assignment. Parameters other - another exception object to assign with Return value *this std::tx_exception::get T get() const transaction_safe; (TM TS) Returns the payload object held by the exception object. Exceptions May throw implementation-defined exceptions. std::tx_exception::what virtual const char* what() const transaction_safe_dynamic noexcept; (TM TS) Returns the explanatory string. Parameters (none) Return value Pointer to a null-terminated string with explanatory information. Inherited from std::runtime_error Inherited from std::exception Member functions destructor destroys the exception object [virtual] (virtual public member function of std::exception) what returns an explanatory string [virtual] (virtual public member function of std::exception) http://cppreference.com 2024.06.10 std::tx_exception(3)
