Types

type JobQueue

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

JobQueue implements the quartz.JobQueue interface, using Elasticsearch as the persistence layer.

func NewJobQueue

func NewJobQueue(ctx context.Context) (*JobQueue, error)

NewJobQueue initializes and returns an empty jobQueue.

func (*JobQueue) Clear

func (jq *JobQueue) Clear() error

Clear clears the job queue.

func (*JobQueue) Get

func (jq *JobQueue) Get(jobKey *quartz.JobKey) (quartz.ScheduledJob, error)

Get returns the scheduled job with the specified key without removing it from the queue.

func (*JobQueue) Head

func (jq *JobQueue) Head() (quartz.ScheduledJob, error)

Head returns the first scheduled job without removing it from the queue.

func (*JobQueue) Pop

func (jq *JobQueue) Pop() (quartz.ScheduledJob, error)

Pop removes and returns the next scheduled job from the queue.

func (*JobQueue) Push

func (jq *JobQueue) Push(job quartz.ScheduledJob) error

Push inserts a new scheduled job to the queue. This method is also used by the Scheduler to reschedule existing jobs that have been dequeued for execution.

func (*JobQueue) Remove

func (jq *JobQueue) Remove(jobKey *quartz.JobKey) (quartz.ScheduledJob, error)

Remove removes and returns the scheduled job with the specified key.

func (*JobQueue) ScheduledJobs

func (jq *JobQueue) ScheduledJobs(matchers []quartz.Matcher[quartz.ScheduledJob]) ([]quartz.ScheduledJob, error)

ScheduledJobs returns the slice of all scheduled jobs in the queue.

func (*JobQueue) Size

func (jq *JobQueue) Size() (int, error)
