func SetLogPath

func SetLogPath(path string)

SetLogPath sets the logging folder path for default cron object.

func Size

func Size() int

Size returns the size of the timed tasks of default cron.

func Start

func Start(name string)

Start starts running the specified timed task named <name>.

Types

type Cron

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

func New

func New() *Cron

New returns a new Cron object with default settings.

func (*Cron) Add

func (c *Cron) Add(pattern string, job func(), name ...string) (*Entry, error)

Add adds a timed task. A unique <name> can be bound with the timed task. It returns and error if the <name> is already used.

func (*Cron) AddOnce

func (c *Cron) AddOnce(pattern string, job func(), name ...string) (*Entry, error)

AddOnce adds a timed task which can be run only once. A unique <name> can be bound with the timed task. It returns and error if the <name> is already used.

func (*Cron) AddSingleton

func (c *Cron) AddSingleton(pattern string, job func(), name ...string) (*Entry, error)

AddSingleton adds a singleton timed task. A singleton timed task is that can only be running one single instance at the same time. A unique <name> can be bound with the timed task. It returns and error if the <name> is already used.

Example
package main

import (
	"github.com/gogf/gf/g/os/gcron"
	"github.com/gogf/gf/g/os/glog"
	"time"
)

func main() {
	gcron.AddSingleton("* * * * * *", func() {
		glog.Println("doing")
		time.Sleep(2 * time.Second)
	})
	select {}
}
Output:
