Types ¶
type Cron ¶
type Cron struct {
// contains filtered or unexported fields
}
Cron
Example ¶
package main
import (
"fmt"
"github.com/CreFire/leaf/timer"
)
func main() {
d := timer.NewDispatcher(10)
// cron expr
cronExpr, err := timer.NewCronExpr("* * * * * *")
if err != nil {
return
}
// cron
var c *timer.Cron
c = d.CronFunc(cronExpr, func() {
fmt.Println("My name is Leaf")
c.Stop()
})
// dispatch
(<-d.ChanTimer).Cb()
}
Output: My name is Leaf
type CronExpr ¶
type CronExpr struct {
// contains filtered or unexported fields
}
Field name | Mandatory? | Allowed values | Allowed special characters ---------- | ---------- | -------------- | -------------------------- Seconds | No | 0-59 | * / , - Minutes | Yes | 0-59 | * / , - Hours | Yes | 0-23 | * / , - Day of month | Yes | 1-31 | * / , - Month | Yes | 1-12 | * / , - Day of week | Yes | 0-6 | * / , -
Example ¶
package main
import (
"fmt"
"github.com/CreFire/leaf/timer"
"time"
)
func main() {
cronExpr, err := timer.NewCronExpr("0 * * * *")
if err != nil {
return
}
fmt.Println(cronExpr.Next(time.Date(
2000, 1, 1,
20, 10, 5,
0, time.UTC,
)))
}
Output: 2000-01-01 21:00:00 +0000 UTC
type Dispatcher ¶
type Dispatcher struct {
ChanTimer chan *Timer
}
one dispatcher per goroutine (goroutine not safe)
func NewDispatcher ¶
func NewDispatcher(l int) *Dispatcher
func (*Dispatcher) CronFunc ¶
func (disp *Dispatcher) CronFunc(cronExpr *CronExpr, _cb func()) *Cron
type Timer ¶
type Timer struct {
// contains filtered or unexported fields
}
Timer
Example ¶
package main
import (
"fmt"
"github.com/CreFire/leaf/timer"
)
func main() {
d := timer.NewDispatcher(10)
// timer 1
d.AfterFunc(1, func() {
fmt.Println("My name is Leaf")
})
// timer 2
t := d.AfterFunc(1, func() {
fmt.Println("will not print")
})
t.Stop()
// dispatch
(<-d.ChanTimer).Cb()
}
Output: My name is Leaf
