# 关系型Map

## 在写map的时候总会遇到要拿下级数据的情况，代码会写得很冗杂，而且lock来lock去的很烦，就直接写一个，虽然interface的效率不太好。

### 其实操作在map_test.go和index_test.go里已经有详细的代码看里面就行

```

package main

import (

	"log"

	"remap"

)

type student struct {

	studentID int    // 学员号

	name      string // 姓名

	sex       int8   // 性别 1男 2女

	age       int8   // 年龄

	score     int8   // 分数

}

func main() {

	var hanmeimei = student{

		studentID: 1111,

		name:      "韩梅梅",

		sex:       2,

		age:       10,

		score:     90,

	}

	var lilei = student{

		studentID: 1112,

		name:      "李雷",

		sex:       1,

		age:       10,

		score:     80,

	}

	var m remap.Map

	m.Store("test", hanmeimei) // 修改操作

	d, _ := m.Load("test")     // 读取

	log.Println(1, d)

	// 1 {1111 韩梅梅 2 10 90}

	m.Delete("test")      //删除

	d, _ = m.Load("test") // 读取

	log.Println(2, d)

	// 

	// 创建索引

	m.Store("hanmeimei", hanmeimei) // 修改操作

	m.Store("lilei", lilei)         // 修改操作

	m.CreateIndex("boys", func(k, v interface{}) bool {

		if v.(student).sex == 1 {

			return true

		}

		return false

	})

	i, _ := m.Index.GetIndex("boys") // 取出索引内容

	log.Println(3, i)

	// 3 &{{true}  {{0 0} 0 0 0 0} {{{0 0} 0 0 0 0} map[]} map[lilei:{1112 李雷 1 10 80}]}

	m.Index.DeleteIndex("boys") // 删除索引

}
