## README

# MultipleTree

## 介绍
Nodejs实现的多叉树库

## APIS

1. select(object)

传入一个对象 判断在多叉树中是否存储了这个对象
return : true/false

2. insert(object)

插入这个对象，true为成功，false则说明已经存在

3. grow(object)

不存在则插入 返回true，存在返回false

4. delete(object)

删除对象

5. clear()

清空字典树

6. walk()

返回整个字典树对象

## 例子

```js
const Tree = require('multiple-tree');

let tree = new Tree();

let a = {
    a:1,
    b:2,
    c:3
}

tree.insert(a);
console.log("tree select ",tree.select(a));

console.log(tree.insert({
    a:1,b:2,c:3,d:4
}));

tree.insert({
    a:1,b:2,c:3,d:5
});
tree.insert({
    a:1,b:2,c:3,d:7
});
tree.grow({
    a:1,b:2,c:3,d:6
});
tree.grow({
    a:1,b:2,c:3,d:8
});
tree.grow({
    a:1,b:2,c:3,d:9
});
tree.grow({
    a:1,b:2,c:3,d:9,e:10
});
console.log(tree.grow({
    a:1,b:2,c:3,d:9,e:10
}));
console.log("tree walk ",JSON.stringify(tree.walk()));
tree.delete({
    a:1,b:2,c:3,d:9,e:10
})
console.log("tree walk ",JSON.stringify(tree.walk()));

```

输出:

``` js
tree select  true
true
false
tree walk  {"1":{"2":{"3":{"4":{},"5":{},"6":{},"7":{},"8":{},"9":{"10":{}}}}}}
tree walk  {"1":{"2":{"3":{"4":{},"5":{},"6":{},"7":{},"8":{},"9":{}}}}}
```
