Template:cpp/error/exception/member of derived

(constructor)	constructs a new {{{1}}} object (public member function)
operator=	replaces the {{{1}}} object (public member function)
what	returns the explanatory string (public member function)

std::{{{1}}}::{{{1}}}

	(1)
{{{1}}}() throw();			(until C++11)
{{{1}}}() noexcept;			(since C++11)
		(2)
{{{1}}}( const {{{1}}}& other ) throw();				(until C++11)
{{{1}}}( const {{{1}}}& other ) noexcept;				(since C++11)

Constructs a new {{{1}}} object with an implementation-defined null-terminated byte string which is accessible through what().

1) Default constructor.

2) Copy constructor. If *this and other both have dynamic type std::{{{1}}} then std::strcmp(what(), other.what()) == 0.(since C++11)

Parameters

other

-

another exception object to copy

std::{{{1}}}::operator=

{{{1}}}& operator=( const {{{1}}}& other ) throw();		(until C++11)
{{{1}}}& operator=( const {{{1}}}& other ) noexcept;		(since C++11)

Assigns the contents with those of other. If *this and other both have dynamic type std::{{{1}}} then std::strcmp(what(), other.what()) == 0 after assignment.(since C++11)

Parameters

other

-

another exception object to assign with

Return value

*this

std::{{{1}}}::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 obtained 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().
