Comparable接口中只有一个抽象方法:int compareTo(Object o);。 实现Comparable的类必须实现compareTo(Object o)方法,两个对象即通过compareTo(Object o)方法的返回值来比较大小。 如果当前对象 this 大于形参对象 o ,则返回正整数, 如果当前对象 this 小于形参对象 o ,则返回负整数, 如果当前对象 this 等于形参对...
map<int, int, MyCompare> m; m.insert(make_pair(1, 10)); m.insert(make_pair(2, 20)); m.insert(make_pair(3, 30)); m.insert(make_pair(4, 40)); m.insert(make_pair(5, 50)); for (map<int, int, MyCompare>::iterator it = m.begin(); it != m.end(); it++) { cout ...
std::map<Key,T,Compare,Allocator>::at T&at(constKey&key); (1)(C++11 起) constT&at(constKey&key)const; (2)(C++11 起) 返回到拥有等于key的关键的元素被映射值的引用。若无这种元素,则抛出std::out_of_range类型异常。 参数 key-要找到的元素的关键...
extract 是更换 map 的关键而不重分配的唯一方式: map<int, string>m{{1,"mango"},{2,"papaya"},{3,"guava"}};autonh=m.extract(2);nh.key()=4;m.insert(move(nh));// m == {{1, "mango"}, {3, "guava"}, {4, "papaya"}} ...
我打算将map的实现容器和map接口分开,创建map的时候可以传递一个实现了interface_map_container接口的对象指针进来,如果这个参数 传0,则默认使用红黑树做实际的容器. 这样做的好处是用户可以根据性能需求传递自己定制的容器类.例如在游戏程序中常见的数据表.一般通过一个索引查询,并且在程序启动时候 ...
