Functions

func DelayAdd

func DelayAdd(ctx context.Context, delay time.Duration, pattern string, job JobFunc, name ...string)

DelayAdd adds a timed task to default cron object after `delay` time.

func DelayAddOnce

func DelayAddOnce(ctx context.Context, delay time.Duration, pattern string, job JobFunc, name ...string)

func GetLogger

func GetLogger() glog.ILogger

GetLogger returns the logger in the cron.

func Remove

func Remove(name string)

Remove deletes scheduled task which named `name`.

func SetLogger(logger glog.ILogger)

SetLogger sets the logger for cron.

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`. If no`name` specified, it starts the entire cron.

func Stop

func Stop(name ...string)

Stop stops running the specified timed task named `name`. If no`name` specified, it stops the entire cron.

Types

type Cron

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

func New() *Cron

New returns a new Cron object with default settings.

func (*Cron) Add

func (c *Cron) Add(ctx context.Context, pattern string, job JobFunc, 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) AddEntry

func (c *Cron) AddEntry(ctx context.Context, pattern string, job JobFunc, times int, isSingleton bool, name ...string) (*Entry, error)

AddEntry creates and returns a new Entry object.

func (*Cron) AddOnce

func (c *Cron) AddOnce(ctx context.Context, pattern string, job JobFunc, 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(ctx context.Context, pattern string, job JobFunc, 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.

func (*Cron) AddTimes

func (c *Cron) AddTimes(ctx context.Context, pattern string, times int, job JobFunc, name ...string) (*Entry, error)

AddTimes adds a timed task which can be run specified times. A unique `name` can be bound with the timed task. It returns and error if the `name` is already used.

func (*Cron) Close

func (c *Cron) Close()

Close stops and closes current cron.

func (*Cron) DelayAdd

func (c *Cron) DelayAdd(ctx context.Context, delay time.Duration, pattern string, job JobFunc, name ...string)

DelayAdd adds a timed task after `delay` time.

func (*Cron) DelayAddEntry

func (c *Cron) DelayAddEntry(ctx context.Context, delay time.Duration, pattern string, job JobFunc, times int, isSingleton bool, name ...string)

DelayAddEntry adds a timed task after `delay` time.

func (*Cron) DelayAddOnce

func (c *Cron) DelayAddOnce(ctx context.Context, delay time.Duration, pattern string, job JobFunc, name ...string)

DelayAddOnce adds a timed task after `delay` time. This timed task can be run only once.
