basic_string& assign(const basic_string& str);

1
#

Effects: Equivalent to *this = str.

2
#

Returns: *this.

basic_string& assign(basic_string&& str) noexcept(allocator_traits<Allocator>::propagate_on_container_move_assignment::value || allocator_traits<Allocator>::is_always_equal::value);

3
#

Effects: Equivalent to *this = std​::​move(str).

4
#

Returns: *this.

basic_string& assign(const basic_string& str, size_type pos, size_type n = npos);

5
#

Throws: out_­of_­range if pos > str.size().

6
#

Effects: Determines the effective length rlen of the string to assign as the smaller of n and str.size() - pos and calls assign(str.data() + pos, rlen).

7
#

Returns: *this.

basic_string& assign(basic_string_view<charT, traits> sv);

8
#

Effects: Equivalent to: return assign(sv.data(), sv.size());

template<class T> basic_string& assign(const T& t, size_type pos, size_type n = npos);

9
#

Throws: out_­of_­range if pos > sv.size().

10
#

Effects: Creates a variable, sv, as if by basic_­string_­view<charT, traits> sv = t. Determines the effective length rlen of the string to assign as the smaller of n and sv.size() - pos and calls assign(sv.data() + pos, rlen).

11
#

Remarks: This function shall not participate in overload resolution unless is_­convertible_­v<const T&, basic_­string_­view<charT, traits>> is true and is_­convertible_­v<const T&, const charT*> is false.

12
#

Returns: *this.

basic_string& assign(const charT* s, size_type n);

13
#

Requires: s points to an array of at least n elements of charT.

14
#

Throws: length_­error if n > max_­size().

15
#

Effects: Replaces the string controlled by *this with a string of length n whose elements are a copy of those pointed to by s.

16
#

Returns: *this.

basic_string& assign(const charT* s);

17
#

Requires: s points to an array of at least traits​::​length(s) + 1 elements of charT.

18
#

Effects: Calls assign(s, traits​::​length(s)).

19
#

Returns: *this.

basic_string& assign(initializer_list<charT> il);

20
#

Effects: Calls assign(il.begin(), il.size()).

21
#

*this.

basic_string& assign(size_type n, charT c);

22
#

Effects: Equivalent to assign(basic_­string(n, c)).

23
#

Returns: *this.

template<class InputIterator> basic_string& assign(InputIterator first, InputIterator last);

24
#

Effects: Equivalent to assign(basic_­string(first, last, get_­allocator())).

25
#

Returns: *this.
