STD:向前[医]名单::剪接[医]后
void splice_after( const_iterator pos, forward_list& other | (1) | (since C++11) |
---|---|---|
void splice_after( const_iterator pos, forward_list&& other | (1) | (since C++11) |
void splice_after( const_iterator pos, forward_list& other, const_iterator it | (2) | (since C++11) |
void splice_after( const_iterator pos, forward_list&& other, const_iterator it | (2) | (since C++11) |
void splice_after( const_iterator pos, forward_list& other, const_iterator first, const_iterator last | (3) | (since C++11) |
void splice_after( const_iterator pos, forward_list&& other, const_iterator first, const_iterator last | (3) | (since C++11) |
从另一个移动元素forward_list
到*this
...
没有复制任何元素。pos
中的有效迭代器。*this
或者是before_begin()
迭代器。如果get_allocator() != other.get_allocator()
没有迭代器或引用失效,移动元素的迭代器现在引用到*this
,而不是进入other
...
1%29移动所有元素other
进*this
。元素插入到pos
.集装箱other
手术后变为空。如果this == &other
2%29移动迭代器指向的元素如下it
从other
进*this
pos
.没有任何效果pos==it
或者如果pos==++it
...
3%29移动范围内的元素(first, last)
从other
进*this
。元素插入到pos
.指向的元素first
不会动。如果pos
是范围内的迭代器。(first,last)
...
参数
pos | - | element after which the content will be inserted |
---|---|---|
other | - | another container to move the content from |
it | - | iterator preceding the iterator to the element to move from other to *this |
first, last | - | the range of elements to move from other to *this |
返回值
%280%29
复杂性
1%29线性other
2%29常数
3%29线性std::distance
(first, last)
例
演示第三种拼接形式中打开间隔%281,最后%29的含义。[医]在%28%29之后:L1的第一个元素没有移动。

#include <iostream>
#include <forward_list>
int main()
{
std::forward_list<int> l1 = {1,2,3,4,5};
std::forward_list<int> l2 = {10,11,12};
l2.splice_after(l2.cbegin(), l1, l1.cbegin(), l1.cend()
// not equivalent to l2.splice_after(l2.cbegin(), l1
for(int n : l1)
std::cout << n << ' ';
std::cout << '\n';
for(int n : l2)
std::cout << n << ' ';
std::cout << '\n';
