Method Details

getRecurrencePeriod

public long getRecurrencePeriod()

Description copied from class: AperiodicWork

Gets the number of milliseconds between successive executions.

Jenkins calls this method every time the timer task is scheduled.

Specified by:

getRecurrencePeriod in class AperiodicWork

getNewInstance

public AperiodicWork getNewInstance()

Description copied from class: AperiodicWork

Gets new instance of task to be executed. Method should return new instance each time, as there no check, if previously scheduled task already finished. Returning same instance could lead to throwing IllegalStateException (especially in case of AsyncAperiodicWork) and therefore scheduling of next tasks will be broken.

Specified by:

getNewInstance in class AperiodicWork

Returns:

AperiodicWork - timer task instance to be executed

doAperiodicRun

protected void doAperiodicRun()

Specified by:

doAperiodicRun in class AperiodicWork
