Functions

func AddEvent

func AddEvent(eventName string, handler func(func(bool), ...interface{}))

添加事件

Types

type EventsInstance

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

var Events *EventsInstance = NewEvents()

func NewEvents

func NewEvents() *EventsInstance

func (*EventsInstance) Delete

func (e *EventsInstance) Delete(eventName string)

func (*EventsInstance) Execute

*

• 顺序执行事件

func (*EventsInstance) GoExecute

func (e *EventsInstance) GoExecute(eventName string, next func(bool), sessions ...interface{})

并发执行事件 [Examle 1:] Events.GoExecute("AfterHandler", func(_ bool) {//此匿名函数在本事件的最后执行

	session.Response.Send()
	session.Response.Close()
}, session)

[Examle 2:] Events.Execute("AfterResponse", func(_ bool) {}, session)

func (*EventsInstance) Register

func (e *EventsInstance) Register(eventName string, handler func(func(bool), ...interface{}))

注册事件 [Examle:]

Events.Register("AfterResponse", func(next func(bool),session ...interface{}) {
	log.Println("Got AfterResponse event!")
	isSuccess := true
	next(isSuccess) //这里的next函数无论什么情况下必须执行。
})

采用不同的方式执行事件时，此处的next函数的作用也是不同的： 1、在并发执行事件的时候，next函数的作用是通知程序我已经执行完了(不理会这一步是否执行成功)； 2、在顺序执行事件的时候，next函数的作用是通知程序是否继续执行下一步，next(true)是继续执行下一步，next(false)是终止执行下一步
