exception& operator=( const exception& other ) throw();
(until C++11)
exception& operator=( const exception& other ) noexcept;
(since C++11) (constexpr since C++26)
Copy assignment operator. Assigns the contents of other.
If *this and other both have dynamic type std::exception then std::strcmp (what(), other.what()) == 0 after assignment.
[edit] Parameters
other
-
another exception to assign the contents of
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 471 | C++98 | the effects of calling what() after assignment are implementation-defined |
required to be the same as the original what() if the dynamic types are the same |
