Types

type EventProducer

type EventProducer struct {
	Context context.Context

	Waiters   map[string]*schedule.Ticker
	EventChan chan *jobs.JobTriggerEvent
	StopChan  chan bool
	TestChan  chan *jobs.JobTriggerEvent
}

EventProducer gathers all Tickers in a pool and provides a single entry point to communicate with them, typically to stop them.

func NewEventProducer

func NewEventProducer(rootCtx context.Context) *EventProducer

NewEventProducer creates a pool of ScheduleWaiters that will send events based on pre-defined scheduling.

func (*EventProducer) Start

func (e *EventProducer) Start() error

Start loads all TimersOnly Jobs from the job repository and registers them in this EventProducer pool.

func (*EventProducer) StartOrUpdateJob

func (e *EventProducer) StartOrUpdateJob(job *jobs.Job)

StartOrUpdateJob creates a ScheduleWaiter and registers it in the EventProducer pool. If a waiter already exists for the same job ID it will be stopped and replaced with a new one.

func (*EventProducer) StopAll

func (e *EventProducer) StopAll()

StopAll ranges all waiters from the EventProducer, calls Stop() and remove them from the Waiter pool.

func (*EventProducer) StopWaiter

func (e *EventProducer) StopWaiter(jobId string)

StopWaiter stops a waiter given its ID and remove it from the Waiter pool. If no waiter with this ID is registered, it returns silently.

type JobsEventsSubscriber

type JobsEventsSubscriber struct {
	Producer *EventProducer
}

JobsEventsSubscriber provides an entry point to add, update or remove Scheduler Jobs.

func (*JobsEventsSubscriber) Handle

Handle passes JobChangeEvents to the registered event producer.
