`apscheduler.jobstores.base`

class apscheduler.jobstores.base.BaseJobStore

Bases: object

Abstract base class that defines the interface that every job store must implement.

abstract add_job(job)

Adds the given job to this store.

Parameters:: job (Job) – the job to add
Raises:: ConflictingIdError – if there is another job in this store with the same ID

abstract get_all_jobs()

Returns a list of all jobs in this job store. The returned jobs should be sorted by next run time (ascending). Paused jobs (next_run_time == None) should be sorted last.

The job store is responsible for setting the scheduler and jobstore attributes of the returned jobs to point to the scheduler and itself, respectively.

Return type:: list[Job]

abstract get_due_jobs(now)

Returns the list of jobs that have next_run_time earlier or equal to now. The returned jobs must be sorted by next run time (ascending).

Parameters:: now (datetime.datetime) – the current (timezone aware) datetime
Return type:: list[Job]

abstract get_next_run_time()

Returns the earliest run time of all the jobs stored in this job store, or None if there are no active jobs.

Return type:: datetime.datetime

abstract lookup_job(job_id)

Returns a specific job, or None if it isn’t found..

The job store is responsible for setting the scheduler and jobstore attributes of the returned job to point to the scheduler and itself, respectively.

Parameters:: job_id (str|unicode) – identifier of the job
Return type:: Job

abstract remove_all_jobs(): Removes all jobs from this store.

abstract remove_job(job_id)

Removes the given job from this store.

Parameters:: job_id (str|unicode) – identifier of the job
Raises:: JobLookupError – if the job does not exist

shutdown(): Frees any resources still bound to this job store.

start(scheduler, alias)

Called by the scheduler when the scheduler is being started or when the job store is being added to an already running scheduler.

Parameters:

scheduler (apscheduler.schedulers.base.BaseScheduler) – the scheduler that is starting this job store
alias (str|unicode) – alias of this job store as it was assigned to the scheduler

abstract update_job(job)

Replaces the job in the store with the given newer version.

Parameters:: job (Job) – the job to update
Raises:: JobLookupError – if the job does not exist

exception apscheduler.jobstores.base.ConflictingIdError(job_id)

Bases: KeyError

Raised when the uniqueness of job IDs is being violated.

exception apscheduler.jobstores.base.JobLookupError(job_id)
