void insert_range ( R && rg ) ; |
(since C++23)
(constexpr since C++26) |
|
Inserts a copy of each element in the range rg .
Each iterator in the range rg is dereferenced exactly once.
If any of the following conditions is satisfied, the behavior is undefined:
-
value_typeis not EmplaceConstructible intomultisetfrom * ranges:: begin ( rg ) - rg and * this overlap.
No iterators or references are invalidated.

Parameters
| rg | - |
a
container compatible range
, that is, an
input_range
whose elements are convertible to
T

Complexity
N·log(S+N) , where S is size ( ) and N is ranges:: distance ( rg ) .

Example
#include <iostream> #include <set> void println(auto, const auto& container) { for (const auto& elem : container) std::cout << elem << ' '; std::cout << '\n'; } int main() { auto container = std::multiset{1, 3, 2, 4}; const auto rg = {-1, 3, -2}; #ifdef __cpp_lib_containers_ranges container.insert_range(rg); #else container.insert(rg.begin(), rg.end()); #endif println("{}", container); }
Output:
-2 -1 1 2 3 3 4
