Constructor Summary

DelegatingLocalityTrigger(Trigger trigger, NodeSpec nodeSpec)
Constructs a LocalityAware Trigger, wrapping an existing Trigger instance, with additional NodeSpec

Method Summary

Object	clone()
int	compareTo(Trigger other) Compare the next fire time of this Trigger to that of another by comparing their keys, or in other words, sorts them according to the natural (i.e.
Date	computeFirstFireTime(Calendar calendar)
Trigger.CompletedExecutionInstruction	executionComplete(JobExecutionContext context, JobExecutionException result)
String	getCalendarName() Get the name of the Calendar associated with this Trigger.
String	getDescription() Return the description given to the Trigger instance by its creator (if any).
Date	getEndTime() Get the time at which the Trigger should quit repeating - regardless of any remaining repeats (based on the trigger's particular repeat settings).
Date	getFinalFireTime() Returns the last time at which the Trigger will fire, if the Trigger will repeat indefinitely, null will be returned.
String	getFireInstanceId()
Date	getFireTimeAfter(Date afterTime) Returns the next time at which the Trigger will fire, after the given time.
JobDataMap	getJobDataMap() Get the JobDataMap that is associated with the Trigger.
JobKey	getJobKey()
TriggerKey	getKey()
int	getMisfireInstruction() Get the instruction the Scheduler should be given for handling misfire situations for this Trigger- the concrete Trigger type that you are using will have defined a set of additional MISFIRE_INSTRUCTION_XXX constants that may be set as this property's value.
Date	getNextFireTime() Returns the next time at which the Trigger is scheduled to fire.
NodeSpec	getNodeSpec() Accessor to the NodeSpec instance to evaluate constraints
Date	getPreviousFireTime() Returns the previous time at which the Trigger fired.
int	getPriority() The priority of a Trigger acts as a tiebreaker such that if two Triggers have the same scheduled fire time, then the one with the higher priority will get first access to a worker thread.

Date	getStartTime() Get the time at which the Trigger should occur.
TriggerBuilder<Trigger>	getTriggerBuilder() Get a TriggerBuilder that is configured to produce a Trigger identical to this one.

Constructor Detail

DelegatingLocalityTrigger

public DelegatingLocalityTrigger(Trigger trigger,
                                 NodeSpec nodeSpec)

Constructs a LocalityAware Trigger, wrapping an existing Trigger instance, with additional NodeSpec

Parameters:

trigger - The Trigger instance to wrap

nodeSpec - The NodeSpec instance

Method Detail

getNodeSpec

public NodeSpec getNodeSpec()

Accessor to the NodeSpec instance to evaluate constraints

Specified by:

getNodeSpec in interface LocalityAware

Returns:

getKey

public TriggerKey getKey()

Specified by:

getKey in interface Trigger

getJobKey

public JobKey getJobKey()

Specified by:

getJobKey in interface Trigger

getDescription

public String getDescription()

Return the description given to the Trigger instance by its creator (if any).

Specified by:

getDescription in interface Trigger

Returns:

null if no description was set.

getCalendarName

public String getCalendarName()

Get the name of the Calendar associated with this Trigger.

Specified by:

getCalendarName in interface Trigger

Returns:

null if there is no associated Calendar.

getJobDataMap

public JobDataMap getJobDataMap()

Get the JobDataMap that is associated with the Trigger.

Changes made to this map during job execution are not re-persisted, and in fact typically result in an IllegalStateException.

Specified by:

getJobDataMap in interface Trigger

getPriority

public int getPriority()

The priority of a Trigger acts as a tiebreaker such that if two Triggers have the same scheduled fire time, then the one with the higher priority will get first access to a worker thread.

If not explicitly set, the default value is 5.

Specified by:

getPriority in interface Trigger

See Also:

Trigger.DEFAULT_PRIORITY

mayFireAgain

public boolean mayFireAgain()

Used by the Scheduler to determine whether or not it is possible for this Trigger to fire again.

If the returned value is false then the Scheduler may remove the Trigger from the JobStore.

Specified by:

mayFireAgain in interface Trigger

getStartTime

public Date getStartTime()

Get the time at which the Trigger should occur.

Specified by:

getStartTime in interface Trigger

getEndTime

public Date getEndTime()

Get the time at which the Trigger should quit repeating - regardless of any remaining repeats (based on the trigger's particular repeat settings).

Specified by:

getEndTime in interface Trigger

See Also:

Trigger.getFinalFireTime()

getNextFireTime

public Date getNextFireTime()

Returns the next time at which the Trigger is scheduled to fire. If the trigger will not fire again, null will be returned. Note that the time returned can possibly be in the past, if the time that was computed for the trigger to next fire has already arrived, but the scheduler has not yet been able to fire the trigger (which would likely be due to lack of resources e.g. threads).

The value returned is not guaranteed to be valid until after the Trigger has been added to the scheduler.

Specified by:

getNextFireTime in interface Trigger

See Also:

TriggerUtils#computeFireTimesBetween(Trigger, Calendar, Date, Date)

getPreviousFireTime

public Date getPreviousFireTime()

Returns the previous time at which the Trigger fired. If the trigger has not yet fired, null will be returned.

Specified by:

getPreviousFireTime in interface Trigger

getFireTimeAfter

public Date getFireTimeAfter(Date afterTime)

Returns the next time at which the Trigger will fire, after the given time. If the trigger will not fire after the given time, null will be returned.

Specified by:

getFireTimeAfter in interface Trigger

getFinalFireTime

public Date getFinalFireTime()

Returns the last time at which the Trigger will fire, if the Trigger will repeat indefinitely, null will be returned.

Note that the return time *may* be in the past.

Specified by:

getFinalFireTime in interface Trigger

getMisfireInstruction

public int getMisfireInstruction()

Get the instruction the Scheduler should be given for handling misfire situations for this Trigger- the concrete Trigger type that you are using will have defined a set of additional MISFIRE_INSTRUCTION_XXX constants that may be set as this property's value.

If not explicitly set, the default value is MISFIRE_INSTRUCTION_SMART_POLICY.

Specified by:

getMisfireInstruction in interface Trigger

See Also:

Trigger.MISFIRE_INSTRUCTION_SMART_POLICY, #updateAfterMisfire(Calendar), SimpleTrigger, CronTrigger

compareTo

public int compareTo(Trigger other)

getTriggerBuilder

public TriggerBuilder<Trigger> getTriggerBuilder()

Get a TriggerBuilder that is configured to produce a Trigger identical to this one.
