成员函数

insert_iterator::insert_iterator

insert_iterator::operator=

insert_iterator::operator*

insert_iterator::operator++insert_iterator::operator++(int)

 

insert_iterator() = default;	(1)	(C++20 起)
	(2)
insert_iterator( Container& c, typename Container::iterator i );			(C++20 前)
constexpr  insert_iterator( Container& c, ranges::iterator_t<Container> i );			(C++20 起)

1) 初始化底层指向容器的指针为 nullptr 并值初始化底层迭代器。

(C++20 起)

2) 初始化底层指向容器指针为 std::addressof(c) 并初始化底层迭代器为 i 。

参数

c	-	用以初始化插入器的容器
i	-	用以初始化插入器的迭代器
