C++ inserting unique_ptr in map

Question

I have a C++ object of type ObjectArray

typedef map> ObjectArray;

What is the syn

Answer 1

In addition to previous answers, I wanted to point out that there is also a method emplace (it's convenient when you cannot/don't want to make a copy), so you can write it like this:

ObjectArray object_array;
auto pointer = std::make_unique(...);  // since C++14
object_array.emplace(239LL, std::move(pointer));
// You can also inline unique pointer:
object_array.emplace(30LL, std::make_unique(...));
