std::vector<T,Allocator>::assign_range - cppreference.com (original) (raw)

Replaces elements in the container with a copy of each element in rg.

All iterators (including the end() iterator) and all references to the elements are invalidated.

Each iterator in the range rg is dereferenced exactly once.

If rg overlaps with *this, the behavior is undefined.
