    public void updateAfterMisfire(Calendar cal)

  Updates the `SimpleTrigger`'s state based on the MISFIRE_INSTRUCTION_XXX that was selected when the `SimpleTrigger` was created.

  If the misfire instruction is set to MISFIRE_INSTRUCTION_SMART_POLICY, then the following scheme will be used:

  - If the Repeat Count is `0`, then the instruction will be interpreted as `MISFIRE_INSTRUCTION_FIRE_NOW`.
  - If the Repeat Count is `REPEAT_INDEFINITELY`, then the instruction will be interpreted as `MISFIRE_INSTRUCTION_RESCHEDULE_NEXT_WITH_REMAINING_COUNT`. WARNING: using MISFIRE_INSTRUCTION_RESCHEDULE_NEXT_WITH_REMAINING_COUNT with a trigger that has a non-null end-time may cause the trigger to never fire again if the end-time arrived during the misfire time span.
  - If the Repeat Count is `> 0`, then the instruction will be interpreted as `MISFIRE_INSTRUCTION_RESCHEDULE_NOW_WITH_EXISTING_REPEAT_COUNT`.

  Specified by:
    `triggered` in class `AbstractTrigger<SimpleTrigger>`

  Description copied from class: `AbstractTrigger`

  This method should not be used by the Quartz client.

  To be implemented by the concrete class.

  The implementation should update the `Trigger`'s state based on the given new version of the associated `Calendar` (the state should be updated so that it's next fire time is appropriate given the Calendar's new settings).

  Specified by:
    `updateWithNewCalendar` in interface `OperableTrigger`
  Specified by:
    `updateWithNewCalendar` in class `AbstractTrigger<SimpleTrigger>`
  Parameters:
    `calendar` - the modifying calendar
  See Also:
    `AbstractTrigger.updateWithNewCalendar(org.quartz.Calendar, long)`

### computeFirstFireTime

    public Date computeFirstFireTime(Calendar calendar)

  Called by the scheduler at the time a `Trigger` is first added to the scheduler, in order to have the `Trigger` compute its first fire time, based on any associated calendar.

  After this method has been called, `getNextFireTime()` should return a valid answer.

  Specified by:
    `computeFirstFireTime` in interface `OperableTrigger`
  Specified by:
    `computeFirstFireTime` in class `AbstractTrigger<SimpleTrigger>`

    the first time at which the `Trigger` will be fired by the scheduler, which is also the same value `getNextFireTime()` will return (until after the first firing of the `Trigger`).

### 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`
  Specified by:
    `getNextFireTime` in class `AbstractTrigger<SimpleTrigger>`
  See Also:

  Specified by:
    `getFireTimeAfter` in class `AbstractTrigger<SimpleTrigger>`

### getFireTimeBefore

    public Date getFireTimeBefore(Date end)

  Returns the last time at which the `SimpleTrigger` will fire, before the given time. If the trigger will not fire before the given time, `null` will be returned.

### computeNumTimesFiredBetween

    public int computeNumTimesFiredBetween(Date start,
                                           Date end)

  Specified by:
    `mayFireAgain` in interface `Trigger`
  Specified by:
    `mayFireAgain` in class `AbstractTrigger<SimpleTrigger>`

### validate

    public void validate()
                  throws SchedulerException

  Validates whether the properties of the `JobDetail` are valid for submission into a `Scheduler`.

  Specified by:
    `validate` in interface `OperableTrigger`
  Overrides:

  Throws:
    `IllegalStateException` - if a required property (such as Name, Group, Class) is not set.
    `SchedulerException`

### hasAdditionalProperties

    public boolean hasAdditionalProperties()

  Used by extensions of SimpleTrigger to imply that there are additional properties, specifically so that extensions can choose whether to be stored as a serialized blob, or as a flattened SimpleTrigger table.
