Returns an iterator past the last element of *this.
This returned iterator only acts as a sentinel. It is not guaranteed to be dereferenceable.

[edit] Return value
Iterator past the last element.
[edit] Complexity
Constant.
[edit] Example
Run this code
#include <iostream> #include <flat_map> int main() { std::flat_multimap <int, int> map{{4, 13}, {9, 94}, {1, 19}, {4, 42}}; for (auto it = map.cbegin(); it != map.cend(); ++it) std::cout << '[' << it->first << "] = " << it->second << '\n'; // Unlike std::multimap's bidirectional iterators, the std::flat_multimap // iterators are random-access, so they can be used with the operator[]: auto it = map.cbegin(); assert (it[1] == 19); assert (it[4] == 13); assert (it[4] == 42); assert (it[9] == 94); }
Output:
[1] = 19 [4] = 13 [4] = 42 [9] = 94
