constexpr basic_string& insert(size_type pos, const basic_string& str);
Effects:Equivalent to: return insert(pos, str.data(), str.size());
constexpr basic_string& insert(size_type pos1, const basic_string& str, size_type pos2, size_type n = npos);
Effects:Equivalent to:
return insert(pos1, basic_string_view<charT, traits>(str), pos2, n);
template<class T> constexpr basic_string& insert(size_type pos, const T& t);
Constraints:
- is_convertible_v<const T&, basic_string_view<charT, traits>> istrue and
- is_convertible_v<const T&, const charT*> isfalse.
Effects:Equivalent to:
basic_string_view<charT, traits> sv = t; return insert(pos, sv.data(), sv.size());
template<class T> constexpr basic_string& insert(size_type pos1, const T& t, size_type pos2, size_type n = npos);
Constraints:
- is_convertible_v<const T&, basic_string_view<charT, traits>> istrue and
- is_convertible_v<const T&, const charT*> isfalse.
Effects:Equivalent to:
basic_string_view<charT, traits> sv = t; return insert(pos1, sv.substr(pos2, n));
constexpr basic_string& insert(size_type pos, const charT* s, size_type n);
Preconditions: [s, s + n) is a valid range.
Throws:
- out_of_range if pos > size(),
- length_error if n > max_size() - size(), or
- any exceptions thrown by allocator_traits<Allocator>::allocate.
Effects:Inserts a copy of the range [s, s + n)immediately before the character at position pos if pos < size(), or otherwise at the end of the string.
constexpr basic_string& insert(size_type pos, const charT* s);
Effects:Equivalent to: return insert(pos, s, traits::length(s));
constexpr basic_string& insert(size_type pos, size_type n, charT c);
Effects:Inserts n copies of c before the character at position posif pos < size(), or otherwise at the end of the string.
Throws:
- out_of_range if pos > size(),
- length_error if n > max_size() - size(), or
- any exceptions thrown by allocator_traits<Allocator>::allocate.
constexpr iterator insert(const_iterator p, charT c);
Preconditions: p is a valid iterator on*this.
Effects:Inserts a copy of c at the position p.
Returns:An iterator which refers to the inserted character.
constexpr iterator insert(const_iterator p, size_type n, charT c);
Preconditions: p is a valid iterator on*this.
Effects:Inserts n copies of c at the position p.
Returns:An iterator which refers to the first inserted character, orp if n == 0.
template<class InputIterator> constexpr iterator insert(const_iterator p, InputIterator first, InputIterator last);
Preconditions: p is a valid iterator on*this.
Effects:Equivalent toinsert(p - begin(), basic_string(first, last, get_allocator())).
Returns:An iterator which refers to the first inserted character, orp if first == last.
constexpr iterator insert(const_iterator p, initializer_list<charT> il);
Effects:Equivalent to: return insert(p, il.begin(), il.end());
