std::list<T,Allocator>::append_range - cppreference.com (original) (raw)

Inserts copies of elements from the range rg before end(), in non-reversing order.

No iterators or references are invalidated.

Each iterator in rg is dereferenced exactly once.

[edit] Parameters

[edit] Complexity

Linear in size of rg. The number of calls to the constructor of T is exactly equal to the std::ranges::size(rg)).

[edit] Exceptions

If an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).

Notes

[edit] Example

#include #include #include   int main() { auto head = std::list{1, 2, 3, 4}; const auto tail = std::vector{-5, -6, -7}; #ifdef __cpp_lib_containers_ranges head.append_range(tail); #else head.insert(head.end(), tail.cbegin(), tail.cend()); #endif assert((head == std::list{1, 2, 3, 4, -5, -6, -7})); }
