std::length_error(3) C++ Standard Libary std::length_error(3) NAME std::length_error - std::length_error Synopsis Defined in header <stdexcept> class length_error; Defines a type of object to be thrown as exception. It reports er- rors that result from attempts to exceed implementation defined length limits for some object. This exception is thrown by member functions of std::basic_string and std::vector::reserve std-length error-inheritance.svg Inheritance diagram Member functions constructor constructs a new length_error object with the given message (public member function) operator= replaces the length_error object (public member function) what returns the explanatory string (public member function) std::length_error::length_error length_error( const std::string& what_arg ); (1) length_error( const char* what_arg ); (2) (since C++11) length_error( const length_error& other ); (3) (until C++11) length_error( const length_error& other ) noexcept; (since C++11) 1-2) Constructs the exception object with what_arg as explanatory string that can be accessed through what(). 3) Copy constructor. If *this and other both have dynamic type std::length_error then std::strcmp(what(), other.what()) == 0. (since C++11) Parameters what_arg - explanatory string other - another exception object to copy Exceptions 1-2) May throw std::bad_alloc Notes Because copying std::length_error is not permitted to throw excep- tions, this message is typically stored internally as a separately-allocated reference- counted string. This is also why there is no constructor taking std::string&&: it would have to copy the content anyway. std::length_error::operator= length_error& operator=( const length_error& other ); (un- til C++11) length_error& operator=( const length_error& other ) noexcept; (since C++11) Assigns the contents with those of other. If *this and other both have dynamic type std::length_error then std::strcmp(what(), other.what()) == 0 after assignment. (since C++11) Parameters other - another exception object to assign with Return value *this std::length_error::what virtual const char* what() const throw(); (until C++11) virtual const char* what() const noexcept; (since C++11) Returns the explanatory string. Parameters (none) Return value Pointer to a null-terminated string with explanatory information. The string is suitable for conversion and display as a std::wstring. The pointer is guaranteed to be valid at least until the exception object from which it is ob- tained is destroyed, or until a non-const member function (e.g. copy assignment operator) on the exception object is called. Notes Implementations are allowed but not required to override what(). Inherited from std::logic_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) See also resize changes the number of characters stored (public member function of std::basic_string<CharT,Traits,Al- locator>) http://cppreference.com 2022.07.31 std::length_error(3)
