Interface IJobStore

Namespace

Quartz.Extensibility

Assembly

Quartz.dll

The interface to be implemented by classes that want to provide a IJob and ITrigger storage mechanism for a scheduler's use.

public interface IJobStore

Remarks

Storage of IJob s and ITrigger s should be keyed on the combination of their name and group for uniqueness.

Properties

Clustered

Whether the IJobStore implementation is clustered.

bool Clustered { get; }

Property Value

bool

Remarks

Read-only, because being clustered is something a store is rather than something it is told: the ADO.NET store reports what Enabled says, and a store that cannot cluster answers false and means it.

EstimatedTimeToReleaseAndAcquireTrigger

How long the IJobStore implementation estimates that it will take to release a trigger and acquire a new one.

TimeSpan EstimatedTimeToReleaseAndAcquireTrigger { get; }

Property Value

TimeSpan

SupportsPersistence

Indicates whether job store supports persistence.

bool SupportsPersistence { get; }

Property Value

bool

Methods

AcquireNextTriggers(TriggerAcquisitionRequest, CancellationToken)

Acquires the next triggers to be fired, respecting execution group limits.

ValueTask<List<IOperableTrigger>> AcquireNextTriggers(TriggerAcquisitionRequest request, CancellationToken cancellationToken = default)

Parameters

request TriggerAcquisitionRequest

What to acquire: the cut-off time, how many, the batching window and the per-execution-group capacity still available.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<List<IOperableTrigger>>

The acquired triggers. The caller copies this list rather than taking it over, so it may be one the store keeps.

Remarks

The returned list stays the store's. The scheduler's acquisition loop copies it before working with it, because it removes entries from its own copy while it waits out the first trigger's fire time and would otherwise be editing something the store still holds. A store is therefore free to hand back a list it keeps a reference to, or to reuse one between calls; it does not have to build a fresh list to be safe. The copy costs the scheduler around ten nanoseconds and sixty-four bytes per acquisition attempt (AcquiredTriggerHandoffBenchmark), against an attempt that is a database round trip, and is kept in preference to a caller-owns rule that every store would have to keep and that would break silently in one that did not (#3344).

AddCalendar(string, ICalendar, AddCalendarOptions, CancellationToken)

Store the given ICalendar.

ValueTask AddCalendar(string calendarName, ICalendar calendar, AddCalendarOptions options = default, CancellationToken cancellationToken = default)

Parameters

calendarName string

The name.

calendar ICalendar

The ICalendar to be stored.

options AddCalendarOptions

Whether an existing calendar of the same name may be over-written, and whether the triggers referencing it have their next fire time re-computed. Defaults to neither.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask

Exceptions

ObjectAlreadyExistsException

A calendar is already stored under the same name and Replace was not asked for.

AddJob(IJobDetail, AddJobOptions, CancellationToken)

Store the given IJobDetail.

ValueTask AddJob(IJobDetail job, AddJobOptions options = default, CancellationToken cancellationToken = default)

Parameters

job IJobDetail

The IJobDetail to be stored.

options AddJobOptions

How to store it. Replace over-writes a job already stored under the same key; without it, storing one whose key exists throws ObjectAlreadyExistsException. StoreNonDurableWhileAwaitingScheduling is a scheduler-level rule that IScheduler has already applied by the time the store is called, so a store neither reads it nor has anything to do about it.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask

AddTrigger(IOperableTrigger, AddTriggerOptions, CancellationToken)

Store the given ITrigger.

ValueTask AddTrigger(IOperableTrigger trigger, AddTriggerOptions options = default, CancellationToken cancellationToken = default)

Parameters

trigger IOperableTrigger

The ITrigger to be stored.

options AddTriggerOptions

How to store it. Replace over-writes a trigger already stored under the same key; without it, storing one whose key exists throws ObjectAlreadyExistsException.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask

Exceptions

ObjectAlreadyExistsException

A trigger is already stored under the same key and Replace was not asked for.

Clear(CancellationToken)

Clear (delete!) all scheduling data - all IJobs, ITriggers and ICalendars.

ValueTask Clear(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

Returns

ValueTask

DeleteCalendar(string, CancellationToken)

Remove (delete) the ICalendar with the given name.

ValueTask<bool> DeleteCalendar(string calendarName, CancellationToken cancellationToken = default)

Parameters

calendarName string

The name of the ICalendar to be removed.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<bool>

true if a ICalendar with the given name was found and removed from the store.

Remarks

If removal of the ICalendar would result in ITriggers pointing to non-existent calendars, then a JobPersistenceException will be thrown.

DeleteJob(JobKey, CancellationToken)

Remove (delete) the IJob with the given key, and any ITrigger s that reference it.

ValueTask<bool> DeleteJob(JobKey jobKey, CancellationToken cancellationToken = default)

Parameters

jobKey JobKey

cancellationToken CancellationToken

Returns

ValueTask<bool>

true if a IJob with the given name and group was found and removed from the store.

Remarks

If removal of the IJob results in an empty group, the group should be removed from the IJobStore's list of known group names.

DeleteJobs(GroupMatcher<JobKey>, CancellationToken)

Remove (delete) every IJob in the matching groups, and any ITriggers that reference them.

ValueTask<List<JobKey>> DeleteJobs(GroupMatcher<JobKey> matcher, CancellationToken cancellationToken = default)

Parameters

matcher GroupMatcher<JobKey>

cancellationToken CancellationToken

Returns

ValueTask<List<JobKey>>

The keys this call removed. A group that matched nothing contributes nothing — an empty list is the plural of the single-key false, not a failure.

Remarks

The default implementation lists the matching keys and then deletes them, which is two operations and so lets a job added in between escape. A store overrides it to resolve the keys and delete them under the same lock or connection scope; the answer must not change when it does.

See Also

DeleteJobs(IReadOnlyCollection<JobKey>, CancellationToken)

DeleteJobs(IReadOnlyCollection<JobKey>, CancellationToken)

Remove (delete) the IJobs with the given keys, and any ITriggers that reference them.

ValueTask<List<JobKey>> DeleteJobs(IReadOnlyCollection<JobKey> jobKeys, CancellationToken cancellationToken = default)

Parameters

jobKeys IReadOnlyCollection<JobKey>

cancellationToken CancellationToken

Returns

ValueTask<List<JobKey>>

The keys this call removed, in the order they were given. A key that names no job is simply absent — the plural of the single-key bool, not a failure.

Remarks

The default implementation walks the set one key at a time. A store overrides it to do the walk inside a single lock or connection scope; the answer must not change when it does.

See Also

DeleteJob(JobKey, CancellationToken)

DeleteTrigger(TriggerKey, CancellationToken)

Remove (delete) the ITrigger with the given key.

ValueTask<bool> DeleteTrigger(TriggerKey triggerKey, CancellationToken cancellationToken = default)

Parameters

triggerKey TriggerKey

cancellationToken CancellationToken

Returns

ValueTask<bool>

true if a ITrigger with the given name and group was found and removed from the store.

Remarks

If removal of the ITrigger results in an empty group, the group should be removed from the IJobStore's list of known group names.

If removal of the ITrigger results in an 'orphaned' IJob that is not 'durable', then the IJob should be deleted also.

DeleteTriggers(GroupMatcher<TriggerKey>, CancellationToken)

Remove (delete) every ITrigger in the matching groups.

ValueTask<List<TriggerKey>> DeleteTriggers(GroupMatcher<TriggerKey> matcher, CancellationToken cancellationToken = default)

Parameters

matcher GroupMatcher<TriggerKey>

cancellationToken CancellationToken

Returns

ValueTask<List<TriggerKey>>

The keys this call removed. A job left orphaned and non-durable by the removal is deleted too, as in the single-key form, but the answer names triggers only.

Remarks

The default implementation lists the matching keys and then deletes them, which is two operations and so lets a trigger added in between escape. A store overrides it to resolve the keys and delete them under the same lock or connection scope; the answer must not change when it does.

See Also

DeleteTriggers(IReadOnlyCollection<TriggerKey>, CancellationToken)

DeleteTriggers(IReadOnlyCollection<TriggerKey>, CancellationToken)

Remove (delete) the ITriggers with the given keys.

ValueTask<List<TriggerKey>> DeleteTriggers(IReadOnlyCollection<TriggerKey> triggerKeys, CancellationToken cancellationToken = default)

Parameters

triggerKeys IReadOnlyCollection<TriggerKey>

cancellationToken CancellationToken

Returns

ValueTask<List<TriggerKey>>

The keys this call removed, in the order they were given. A key that names no trigger is simply absent — the plural of the single-key bool, not a failure. A job left orphaned and non-durable by the removal is deleted too, as in the single-key form, but the answer names triggers only.

Remarks

The default implementation walks the set one key at a time. A store overrides it to do the walk inside a single lock or connection scope; the answer must not change when it does.

DeleteTrigger(TriggerKey, CancellationToken)

Exists(JobKey, CancellationToken)

Determine whether a IJob with the given identifier already exists within the scheduler.

ValueTask<bool> Exists(JobKey jobKey, CancellationToken cancellationToken = default)

Parameters

jobKey JobKey

the identifier to check for

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<bool>

true if a job exists with the given identifier

Exists(TriggerKey, CancellationToken)

Determine whether a ITrigger with the given identifier already exists within the scheduler.

ValueTask<bool> Exists(TriggerKey triggerKey, CancellationToken cancellationToken = default)

Parameters

triggerKey TriggerKey

the identifier to check for

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<bool>

true if a trigger exists with the given identifier

Exists(string, CancellationToken)

Determine whether an ICalendar with the given name already exists within the store.

ValueTask<bool> Exists(string calendarName, CancellationToken cancellationToken = default)

Parameters

calendarName string

the name to check for

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<bool>

true if a calendar is stored under the given name

Remarks

Answer this without materializing the calendar. GetCalendar(string, CancellationToken) can answer it too, but only by reading the stored blob and deserializing it to throw it away — which is what a store implementing this member as GetCalendar(name) is not null would go on doing.

GetAcquireRetryDelay(int)

Get the amount of time to wait when accessing this job store repeatedly fails.

TimeSpan GetAcquireRetryDelay(int failureCount)

Parameters

failureCount int

the number of successive failures seen so far

Returns

TimeSpan

the time to wait before trying again

Remarks

Called by the executor thread(s) when calls to AcquireNextTriggers fail more than once in succession, and the thread thus wants to wait a bit before trying again, to not consume 100% CPU, write huge amounts of errors into logs, etc. in cases like the DB being offline/restarting.

The delay returned by implementations should be between 20 milliseconds and 10 minutes.

GetCalendar(string, CancellationToken)

Retrieve the given ICalendar.

ValueTask<ICalendar?> GetCalendar(string calendarName, CancellationToken cancellationToken = default)

Parameters

calendarName string

The name of the ICalendar to be retrieved.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<ICalendar>

The desired ICalendar, or null if there is no match.

GetJob(JobKey, CancellationToken)

Retrieve the IJobDetail for the given IJob.

ValueTask<IJobDetail?> GetJob(JobKey jobKey, CancellationToken cancellationToken = default)

Parameters

jobKey JobKey

cancellationToken CancellationToken

Returns

ValueTask<IJobDetail>

The desired IJob, or null if there is no match.

GetJobs(IReadOnlyCollection<JobKey>, CancellationToken)

Retrieves the given jobs in one round trip. Keys that do not exist are simply absent from the result.

ValueTask<List<IJobDetail>> GetJobs(IReadOnlyCollection<JobKey> jobKeys, CancellationToken cancellationToken = default)

Parameters

jobKeys IReadOnlyCollection<JobKey>

The keys of the jobs to retrieve.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<List<IJobDetail>>

GetTrigger(TriggerKey, CancellationToken)

Retrieve the given ITrigger.

ValueTask<IOperableTrigger?> GetTrigger(TriggerKey triggerKey, CancellationToken cancellationToken = default)

Parameters

triggerKey TriggerKey

cancellationToken CancellationToken

Returns

ValueTask<IOperableTrigger>

The desired ITrigger, or null if there is no match.

GetTriggerState(TriggerKey, CancellationToken)

Get the current state of the identified ITrigger.

ValueTask<TriggerState> GetTriggerState(TriggerKey triggerKey, CancellationToken cancellationToken = default)

Parameters

triggerKey TriggerKey

cancellationToken CancellationToken

Returns

ValueTask<TriggerState>

See Also

TriggerState

GetTriggers(IReadOnlyCollection<TriggerKey>, CancellationToken)

Retrieves the given triggers in one round trip. Keys that do not exist are simply absent from the result.

ValueTask<List<IOperableTrigger>> GetTriggers(IReadOnlyCollection<TriggerKey> triggerKeys, CancellationToken cancellationToken = default)

Parameters

triggerKeys IReadOnlyCollection<TriggerKey>

The keys of the triggers to retrieve.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<List<IOperableTrigger>>

GetTriggersForJob(JobKey, CancellationToken)

Get all the Triggers that are associated to the given Job.

ValueTask<List<IOperableTrigger>> GetTriggersForJob(JobKey jobKey, CancellationToken cancellationToken = default)

Parameters

jobKey JobKey

cancellationToken CancellationToken

Returns

ValueTask<List<IOperableTrigger>>

Remarks

If there are no matches, a zero-length array should be returned.

Initialize(SchedulerIdentity, CancellationToken)

Called before the IJobStore is used, to give it a chance to initialize.

ValueTask Initialize(SchedulerIdentity identity, CancellationToken cancellationToken = default)

Parameters

identity SchedulerIdentity

The scheduler this store stores for, and the node it is running on. A store records the instance id against the firings this node owns, so that QueryFireInstances(FireInstanceQuery, CancellationToken) can say which node is running what.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask

Remarks

Nearly everything a job store needs — the type loader, the signaler, the time provider — is supplied through its constructor. What remains here is the scheduler's identity, which is not settled until the container has built the graph, and work that has to happen before the scheduler runs and cannot be done during construction, such as verifying a database schema.

PauseAll(CancellationToken)

Pause all triggers - equivalent of calling PauseTriggerGroups(GroupMatcher<TriggerKey>, CancellationToken) on every group.

When ResumeAll(CancellationToken) is called (to un-pause), trigger misfire instructions WILL be applied.

ValueTask PauseAll(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

Returns

ValueTask

See Also

ResumeAll(CancellationToken)

PauseJob(JobKey, CancellationToken)

Pause the IJob with the given key - by pausing all of its current ITriggers.

ValueTask<bool> PauseJob(JobKey jobKey, CancellationToken cancellationToken = default)

Parameters

jobKey JobKey

cancellationToken CancellationToken

Returns

ValueTask<bool>

true if the job exists — including a job that currently has no triggers — false if there is no job with the given key.

PauseJobGroups(GroupMatcher<JobKey>, CancellationToken)

Pause the job groups that match - by pausing all of the ITriggers of the IJobs in them.

ValueTask<List<string>> PauseJobGroups(GroupMatcher<JobKey> matcher, CancellationToken cancellationToken = default)

Parameters

matcher GroupMatcher<JobKey>

cancellationToken CancellationToken

Returns

ValueTask<List<string>>

The names of the job groups that are recorded as paused by this call.

Remarks

The JobStore should "remember" that the group is paused, and impose the pause on any new jobs that are added to the group while the group is paused. That memory is what this answers with — the names of the groups now recorded as paused, which is not the set of keys that moved: an equality matcher records a group that holds no job yet.

PauseJobs(IReadOnlyCollection<JobKey>, CancellationToken)

Pause the IJobs with the given keys - by pausing all of their current ITriggers.

ValueTask<List<JobKey>> PauseJobs(IReadOnlyCollection<JobKey> jobKeys, CancellationToken cancellationToken = default)

Parameters

jobKeys IReadOnlyCollection<JobKey>

cancellationToken CancellationToken

Returns

ValueTask<List<JobKey>>

The keys this call found, in the order they were given — a job with no triggers is found and so is present. A key that names no job is simply absent — the plural of the single-key bool, not a failure.

Remarks

The default implementation walks the set one key at a time. A store overrides it to do the walk inside a single lock or connection scope; the answer must not change when it does.

See Also

PauseJob(JobKey, CancellationToken)

PauseTrigger(TriggerKey, CancellationToken)

Pause the ITrigger with the given key.

ValueTask<bool> PauseTrigger(TriggerKey triggerKey, CancellationToken cancellationToken = default)

Parameters

triggerKey TriggerKey

cancellationToken CancellationToken

Returns

ValueTask<bool>

true if the trigger exists and was moved into the paused state by this call, false if there is no trigger with the given key, it was already paused, or it is in a state that cannot be paused (e.g. complete).

PauseTriggerGroups(GroupMatcher<TriggerKey>, CancellationToken)

Pause the trigger groups that match, and every ITrigger in them.

ValueTask<List<string>> PauseTriggerGroups(GroupMatcher<TriggerKey> matcher, CancellationToken cancellationToken = default)

Parameters

matcher GroupMatcher<TriggerKey>

cancellationToken CancellationToken

Returns

ValueTask<List<string>>

The names of the trigger groups that are recorded as paused by this call.

Remarks

The JobStore should "remember" that the group is paused, and impose the pause on any new triggers that are added to the group while the group is paused. That memory is what this answers with — the names of the groups now recorded as paused, which is not the set of keys that moved: an equality matcher records a group that holds no trigger yet.

PauseTriggers(IReadOnlyCollection<TriggerKey>, CancellationToken)

Pause the ITriggers with the given keys.

ValueTask<List<TriggerKey>> PauseTriggers(IReadOnlyCollection<TriggerKey> triggerKeys, CancellationToken cancellationToken = default)

Parameters

triggerKeys IReadOnlyCollection<TriggerKey>

cancellationToken CancellationToken

Returns

ValueTask<List<TriggerKey>>

The keys this call moved into the paused state, in the order they were given. A key that names no trigger, one that was already paused, and one in a state that cannot be paused are each simply absent — the plural of the single-key bool, not a failure.

Remarks

The default implementation walks the set one key at a time. A store overrides it to do the walk inside a single lock or connection scope; the answer must not change when it does.

PauseTrigger(TriggerKey, CancellationToken)

QueryCalendarNames(CalendarQuery, CancellationToken)

Lists calendar names matching the query, ordered by name (ordinal).

ValueTask<PagedResult<string>> QueryCalendarNames(CalendarQuery query, CancellationToken cancellationToken = default)

Parameters

query CalendarQuery

Which names to select and which page of them to return.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<PagedResult<string>>

QueryClusterNodes(CancellationToken)

Lists the scheduler nodes this store knows about, as ClusterNodes: the current node first, then the rest by instance id (ordinal).

ValueTask<List<ClusterNode>> QueryClusterNodes(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<List<ClusterNode>>

Remarks

The current node is always in the list, whether or not the store has a record of it yet, and it is the only one whose IsCurrentNode is true. A store that keeps no check-in history — the in-memory one, and a persistent one that is not clustered — answers with that single node, Alive and with no times, because a lone node has nobody to be late for.

A clustered store reports every node it has a check-in record for, including nodes that are dead but not yet swept, and decides State with the same predicate its recovery pass uses — so a node this listing calls Failed is a node whose work the cluster is about to take over, rather than one that merely looks late to a second opinion.

Unpaged, because a cluster is a handful of nodes rather than a data set; the listing that does need paging is QueryFireInstances(FireInstanceQuery, CancellationToken), which reports what each node is running.

QueryFireInstances(FireInstanceQuery, CancellationToken)

Lists firings matching the query, as FireInstances, ordered by trigger group, then trigger name, then fire instance id (all ordinal).

ValueTask<PagedResult<FireInstance>> QueryFireInstances(FireInstanceQuery query, CancellationToken cancellationToken = default)

Parameters

query FireInstanceQuery

What to select and which page of it to return.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<PagedResult<FireInstance>>

Remarks

The tiebreaker is what makes a page deterministic here: one trigger can have several firings in flight, so a store must not collapse them and must not order two of them arbitrarily.

A store that keeps firings durably answers for the whole cluster; the in-memory store answers for its own process, which is the whole of its world. Either way the reported SchedulerInstanceId is the id the owning node was initialized with.

QueryJobGroups(JobGroupQuery, CancellationToken)

Lists job groups matching the query, ordered by name (ordinal).

ValueTask<PagedResult<JobGroup>> QueryJobGroups(JobGroupQuery query, CancellationToken cancellationToken = default)

Parameters

query JobGroupQuery

What to select and which page of it to return.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<PagedResult<JobGroup>>

QueryJobs(JobQuery, CancellationToken)

Lists jobs matching the query, as JobHeaders, ordered by group and then name (ordinal).

ValueTask<PagedResult<JobHeader>> QueryJobs(JobQuery query, CancellationToken cancellationToken = default)

Parameters

query JobQuery

What to select and which page of it to return.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<PagedResult<JobHeader>>

Remarks

A listing must not load or deserialize job data. When the query sets IncludeTotalCount, the result carries the total number of matching jobs regardless of paging.

QueryTriggerGroups(TriggerGroupQuery, CancellationToken)

Lists trigger groups matching the query, ordered by name (ordinal).

ValueTask<PagedResult<TriggerGroup>> QueryTriggerGroups(TriggerGroupQuery query, CancellationToken cancellationToken = default)

Parameters

query TriggerGroupQuery

What to select and which page of it to return.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<PagedResult<TriggerGroup>>

Remarks

With Paused set to true, the listing reports every paused group, including a group that is paused but currently has no triggers.

QueryTriggers(TriggerQuery, CancellationToken)

Lists triggers matching the query, as TriggerHeaders, ordered by group and then name (ordinal).

ValueTask<PagedResult<TriggerHeader>> QueryTriggers(TriggerQuery query, CancellationToken cancellationToken = default)

Parameters

query TriggerQuery

What to select and which page of it to return.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<PagedResult<TriggerHeader>>

Remarks

A listing must not materialize triggers or their job data. The header carries the trigger's current state and execution group, so listing callers need no further round trips.

ReleaseAcquiredTrigger(IOperableTrigger, CancellationToken)

Inform the IJobStore that the scheduler no longer plans to fire the given ITrigger, that it had previously acquired (reserved).

ValueTask ReleaseAcquiredTrigger(IOperableTrigger trigger, CancellationToken cancellationToken = default)

Parameters

trigger IOperableTrigger

cancellationToken CancellationToken

Returns

ValueTask

ReplaceTrigger(TriggerKey, IOperableTrigger, CancellationToken)

Remove (delete) the ITrigger with the given name, and store the new given one - which must be associated with the same job.

ValueTask<bool> ReplaceTrigger(TriggerKey triggerKey, IOperableTrigger trigger, CancellationToken cancellationToken = default)

Parameters

triggerKey TriggerKey

The ITrigger to be replaced.

trigger IOperableTrigger

The new ITrigger to be stored.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask<bool>

true if a ITrigger was stored under triggerKey and has been replaced by trigger.

ResetTriggerFromErrorState(TriggerKey, CancellationToken)

Reset the current state of the identified ITrigger from Error to Normal or Paused as appropriate.

ValueTask<bool> ResetTriggerFromErrorState(TriggerKey triggerKey, CancellationToken cancellationToken = default)

Parameters

triggerKey TriggerKey

cancellationToken CancellationToken

Returns

ValueTask<bool>

true if the trigger existed in the error state and was reset by this call, false if there is no trigger with the given key or it was not in the error state.

Remarks

Only affects triggers that are in Error state - if identified trigger is not in that state then the result is a no-op.

The result will be the trigger returning to the normal, waiting to be fired state, unless the trigger's group has been paused, in which case it will go into the Paused state.

See Also

TriggerState

ResetTriggersFromErrorState(IReadOnlyCollection<TriggerKey>, CancellationToken)

Reset every one of the identified ITriggers from Error to Normal or Paused as appropriate.

ValueTask<List<TriggerKey>> ResetTriggersFromErrorState(IReadOnlyCollection<TriggerKey> triggerKeys, CancellationToken cancellationToken = default)

Parameters

triggerKeys IReadOnlyCollection<TriggerKey>

cancellationToken CancellationToken

Returns

ValueTask<List<TriggerKey>>

The keys this call reset, in the order they were given. A key that names no trigger, or one that was not in the error state, is simply absent — the plural of the single-key bool, not a failure.

Remarks

The default implementation walks the set one key at a time. A store overrides it to do the walk inside a single lock or connection scope; the answer must not change when it does.

See Also

ResetTriggerFromErrorState(TriggerKey, CancellationToken)

ResumeAll(CancellationToken)

Resume (un-pause) all triggers - equivalent of calling ResumeTriggerGroups(GroupMatcher<TriggerKey>, CancellationToken) on every group.

If any ITrigger missed one or more fire-times, then the ITrigger's misfire instruction will be applied.

true if the job exists — including a job that currently has no triggers — false if there is no job with the given key.

ResumeJobGroups(GroupMatcher<JobKey>, CancellationToken)

Resume (un-pause) the job groups that match, and the IJobs in them.

If any of the IJob s had ITrigger s that missed one or more fire-times, then the ITrigger's misfire instruction will be applied.

Parameters

jobKeys IReadOnlyCollection<JobKey>

cancellationToken CancellationToken

Returns

ValueTask<List<JobKey>>

The keys this call found, in the order they were given — a job with no triggers is found and so is present. A key that names no job is simply absent — the plural of the single-key bool, not a failure.

Remarks

If any of the jobs' ITriggers missed one or more fire-times, then those triggers' misfire instructions will be applied.

The default implementation walks the set one key at a time. A store overrides it to do the walk inside a single lock or connection scope; the answer must not change when it does.

ResumeTrigger(TriggerKey, CancellationToken)

ScheduleJob(IJobDetail, IOperableTrigger, CancellationToken)

Store the given IJobDetail and ITrigger.

ValueTask ScheduleJob(IJobDetail job, IOperableTrigger trigger, CancellationToken cancellationToken = default)

Parameters

job IJobDetail

The IJobDetail to be stored.

trigger IOperableTrigger

The ITrigger to be stored.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask

Exceptions

A job or a trigger is already stored under one of the two keys. Nothing is stored.

ScheduleJobs(IReadOnlyDictionary<IJobDetail, IReadOnlyCollection<IOperableTrigger>>, ScheduleJobOptions, CancellationToken)

Store all the given jobs with their related triggers.

ValueTask ScheduleJobs(IReadOnlyDictionary<IJobDetail, IReadOnlyCollection<IOperableTrigger>> triggersAndJobs, ScheduleJobOptions options = default, CancellationToken cancellationToken = default)

Parameters

triggersAndJobs IReadOnlyDictionary<IJobDetail, IReadOnlyCollection<IOperableTrigger>>

The jobs to store, each with the triggers that fire it. IOperableTrigger, like the rest of the store contract — the scheduler validates and downcasts the caller's triggers before they reach the store.

options ScheduleJobOptions

How to store them. Replace over-writes any job or trigger already stored under one of the same keys; without it, a key that exists throws ObjectAlreadyExistsException and none of the batch is stored.

cancellationToken CancellationToken

The cancellation instruction.

Returns

ValueTask
