WebIl rimbalzo invalida gli iteratori, modifica l'ordine tra gli elementi e le modifiche in cui gli elementi vengono visualizzati, ma non invalida i puntatori o riferimenti agli elementi. Per unordered_multiset e unordered_multimap, il rehashing mantiene l'ordine relativo di elementi equivalenti. Insomma per unordered_map, Web也就是说,我在构造函数中设置了bucket的数量(不介意它实际上可能会变大),并插入新数据(如果还没有),方法如下: 如果数据所属的bucket不是空的,我将用插入的数据替换它的节点(通过C++17提取插入模式) 否则,我只需插入数据 模拟此方法的最小示例如下所示: #include #include ...
