multi_index_container是c++ boost库中的一个多索引的容器。因工作中用到了,特来测试试用。 1 #include "stdafx.h" 2 #include "test.h" 3 4 #include <string> 5 #include <iostream> 6 #include <boost/multi_index_container.hpp> 7 #include <boost/multi_index/member.hpp> 8 #include <boost/...
下面是如何从 boost::multi_index_container 检索元素的方法: 定义一个 boost::multi_index_container 对象,并为其添加一个或多个索引。索引可以是基于某个字段的排序索引,也可以是基于某个字段的哈希索引,或者是自定义的索引。 代码语言:txt 复制 #include <boost/multi_index_container.hpp> #include <boost/...
#include<boost/multi_index_container.hpp> #include<boost/multi_index/ordered_index.hpp> #include<boost/multi_index/member.hpp> #include<iostream> structPerson{ std::string name; intage; }; intmain(){ // 定义多索引容器,使用复合键 boost::multi_index_container< Person, boost::multi_index::...
Boost Multi-index Containers Library定义了multi_index_container模板类,可以从不同的维度建索引、排序和存取。 如上图,容器multi_index_container分别从shape,number和sequenced(默认插入的顺序)三个维度对元素进行管理。 #include <string>#include <iostream>#include <boost/multi_index_container.hpp>#include <boo...
using boost::multi_index_container ; using namespace boost::multi_index ; using namespace std; using namespace boost; // 玩家信息 class CPlayer { public: CPlayer(int id, string name, int fight, int gold):id(id),name(name),fight(fight),gold(gold) ...
使用boost::multi_index_container来保留插入顺序,可以通过在容器中添加一个额外的索引来实现。这个索引可以是一个整数,表示元素的插入顺序。以下是一个简单的示例: 代码语言:cpp 复制 #include<boost/multi_index_container.hpp> #include<boost/multi_index/ordered_index.hpp> #include<boost/multi_index/id...
typedef boost::multi_index_container<Student,boost::multi_index::indexed_by< boost::multi_index::ordered_unique<boost::multi_index::member<Student,int,&Student::id>>,//id唯一 boost::multi_index::ordered_unique<boost::multi_index::member<Student,string,&Student::name>>, ...
If you look at the logs for the container (docker logs -f <container-id>), you should see a message similar to the following, which indicates it's using the mysql database. $nodemon src/index.js[nodemon] 2.0.20[nodemon] to restart at any time, enter `rs`[nodemon] watching dir(s)...
Containers, by default, run in isolation. They don't know anything about other processes or containers on the same computer. To allow one container to talk to another, use networking. If two containers are on the same network, they can talk to each other. If they aren't, they can't....
Or start ArangoDB in a Docker container: docker run -e ARANGO_ROOT_PASSWORD=test123 -p 8529:8529 -d arangodb Then point your browser tohttp://127.0.0.1:8529/. Key Features of ArangoDB Native Graph- Store both data and relationships, for faster queries even with multiple levels of joins...
