std::map，而不是 stl::map:) 第二个将一个映射复制到另一个映射可以使用operator =或复制构造函数完成。 例如 map<X, Y> mp1; //fill mp1 with data map<X, Y> mp2(mp1); //mp2 is a copy of mp1 (via copy-construction) map<X, Y> mp3; mp3 = mp2; // mp3 is also a ...

std::map<std::string,constValue*> getValues(); (One has a const the other one doesn't. It's kind of dumb that this matters, but it makes my compiler barf.) I just removed the const from the std::string part of the template type to make it compile. ...

std::map是C++标准库中的一个关联容器,它提供了一种键值对的映射关系。在std::map中,键是唯一的且有序的,这意味着每个键只能在std::map中出现一次,并且它们按照一定的顺序进行排序。...
