ソシャゲの不具合の説明に C++ のソースコード？！

CardDatas CardModel::getMasterCardDatasByIds(const std::vector<uint32_t>& masterCardIds) const { vector<CardDataPtr> results; results.resize(masterCardIds.size()); size_t exists = 0; for (int i = 0; i < masterCardIds.size(); i++){ auto p = results[i] = _cardDataCache.fetch(masterCardIds[i]); if (p ! = nullptr){ exists++; } } if (masterCardIds.size() == exists) { return results; } string sql = form("SELECT * FROM cache.cards where id IN (%s);", join(masterCardIds,", ").c_str()); int i = 0; DatabaseManager::getlnstance()->query(sql, [this, &results, &i](sqlite3_stmt* stmt){ if(results[i] == nullptr){ results[i] = _cardDataCache.store(make_shared<CardData>(stmt)); } i++; }); return results; }
