Functions

func AddCleaner

func AddCleaner(key string, ec ExitCleaner) error

添加清理器到默认清理列表

func Exit

func Exit(n int)

默认清理列表退出函数

Types

type CleanList

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

定义清理列表

func NewCleanList

func NewCleanList() *CleanList

创建一个新的清理列表

func (*CleanList) Add

func (p *CleanList) Add(key string, ec ExitCleaner) error

将清理加入列表

func (*CleanList) Exit

func (p *CleanList) Exit(n int, f func(key interface{}, value interface{}) bool)

清理列表的退出方法，调用传入的回调函数 清理器的签名方法将在回调函数中执行

type Cleaner

type Cleaner struct {
	F func() // 回调函数
}

定义清理器

func (*Cleaner) ExitClean

func (p *Cleaner) ExitClean() error

实现清理器接口 在此方法中调用回调函数

func (*Cleaner) HandleFunc

func (p *Cleaner) HandleFunc(f func())

添加回调函数

type ExitCleaner

type ExitCleaner interface {
	ExitClean() error // 清理方法签名，清理器实际执行的逻辑在该方法中实现
}

定义清理器接口
