Tilføjelse af et BSON-array til et MongoDB 3.2-dokument og udpakning af værdierne ( MongoCXX 3.2 ) ( C++ 11)

Brug open_array for at tilføje array til at streame dokument :

  using bsoncxx::builder::stream::document;
  using bsoncxx::builder::stream::open_array;
  using bsoncxx::builder::stream::close_array;
  using bsoncxx::builder::stream::finalize;

  document data_builder{};
  data_builder << "_id" << 5;
  auto array_builder = data_builder << "my_array" << open_array;
  for (float i = 0 ; i < 5 ; i = i + 0.1f) {
    array_builder << i;
  }
  array_builder << close_array;
  bsoncxx::document::value doc = data_builder << finalize;
  std::cout << bsoncxx::to_json(doc) << std::endl;
