在Go語(yǔ)言中,事件處理通常涉及到狀態(tài)管理。為了有效地管理狀態(tài),你可以采用以下方法:
type EventHandler struct {
state int
}
func (h *EventHandler) handleEvent(event string) {
switch event {
case "increment":
h.state++
case "decrement":
h.state--
default:
fmt.Println("Unknown event")
}
}
import "sync"
type EventHandler struct {
state int
mu sync.Mutex
}
func (h *EventHandler) handleEvent(event string) {
h.mu.Lock()
defer h.mu.Unlock()
switch event {
case "increment":
h.state++
case "decrement":
h.state--
default:
fmt.Println("Unknown event")
}
}
type EventHandler struct {
state int
}
func (h *EventHandler) handleEvent(event string, ch chan<- int) {
switch event {
case "increment":
ch <- h.state + 1
case "decrement":
ch <- h.state - 1
default:
fmt.Println("Unknown event")
}
}
func main() {
handler := &EventHandler{}
eventCh := make(chan string)
go handler.handleEvent("increment", eventCh)
go handler.handleEvent("decrement", eventCh)
for i := 0; i < 2; i++ {
event := <-eventCh
fmt.Println("Event received:", event)
}
}
type State interface {
HandleEvent(handler *EventHandler, event string)
}
type IncrementState struct{}
func (s *IncrementState) HandleEvent(handler *EventHandler, event string) {
if event == "increment" {
handler.state++
} else if event == "decrement" {
handler.state--
}
}
type DecrementState struct{}
func (s *DecrementState) HandleEvent(handler *EventHandler, event string) {
if event == "increment" {
handler.state++
} else if event == "decrement" {
handler.state--
}
}
type EventHandler struct {
state State
}
func (h *EventHandler) SetState(state State) {
h.state = state
}
func (h *EventHandler) HandleEvent(event string) {
h.state.HandleEvent(h, event)
}
這些方法可以幫助你在Go語(yǔ)言中有效地管理事件處理的狀態(tài)。你可以根據(jù)具體需求選擇合適的方法。
