concurrent_unordered_map::cend Method 傳回const 所指向之位置的 Iterator 成功最後一個項目在並行容器。 這個方法是並行安全的。 concurrent_unordered_map::clear Method 清除在並行容器的所有項目。 這個函式不是並行安全的。 concurrent_unordered_map::count Method 計算符合指定索引鍵的項目數目。 這個函式是並行...
map<FiveOfFive, int> mm; } The most significant part of the implementation is theconstruct_aritytemplate, which I unashamedly copied from somewhere. This count the number of fields inside a class, by binary searching the amount of field and check if we can construct the object from that man...
Unfortunately, there is no serial counterpart method for find() similar to concurrent_hash_map::equal_range(). BTW, I would add serial interfaces for all the concurrent containers but our architect is against it. He doubts it has more advantages than potential problems. As for the load facto...
