Types

type Analysis

type Analysis struct{}

func (*Analysis) Visit

func (a *Analysis) Visit()

type Container

type Container struct {
	// contains filtered or unexported fields
}

创建容器

func (*Container) Add

func (c *Container) Add(visitor Visitor)

func (*Container) Remove

func (c *Container) Remove(index int)

type Iterator

type Iterator struct {
	Container
	// contains filtered or unexported fields
}

设计思想：
	1. Iterator结构体
		实现Next()  HasNext()方法
	2. Container容器
		容器实现添加 移除Visitor 和
