Class SchedulerAdapter

java.lang.Object
  org.cishell.app.service.scheduler.SchedulerAdapter

All Implemented Interfaces:

SchedulerListener

public abstract class SchedulerAdapter
extends Object
implements SchedulerListener

An abstract adapter class for notification of events happening in a SchedulerService. The methods in this class are empty. This class exists as a convenience for creating listener objects.

void	algorithmScheduled(Algorithm algorithm, Calendar time) Notification that an Algorithm has been scheduled to be run at a certain time
void	algorithmStarted(Algorithm algorithm) Notification that an Algorithm has started execution
void	algorithmUnscheduled(Algorithm algorithm) Notification that an already scheduled Algorithm has been unscheduled and will therefore not be run

Description copied from interface: SchedulerListener

Notification that an Algorithm had an error while being executed

Specified by:

algorithmError in interface SchedulerListener

Parameters:

algorithm - The scheduled Algorithm

error - The error it threw while executing

algorithmFinished

public void algorithmFinished(Algorithm algorithm,
                              Data[] createdData)

Description copied from interface: SchedulerListener

Notification that an Algorithm has finished executing

Specified by:

algorithmFinished in interface SchedulerListener

Parameters:

algorithm - The scheduled Algorithm

createdData - The Data array it returned, or null if it returned null

algorithmRescheduled

public void algorithmRescheduled(Algorithm algorithm,
                                 Calendar time)

Description copied from interface: SchedulerListener

Notification that an already scheduled Algorithm has been rescheduled to be run at a different time

Specified by:

algorithmRescheduled in interface SchedulerListener

Parameters:

algorithm - The scheduled Algorithm

time - The new time the Algorithm is scheduled to be run

algorithmUnscheduled

public void algorithmUnscheduled(Algorithm algorithm)

Description copied from interface: SchedulerListener

Notification that an already scheduled Algorithm has been unscheduled and will therefore not be run

Specified by:

algorithmUnscheduled in interface SchedulerListener

Parameters:

algorithm - The scheduled Algorithm that was unscheduled

algorithmScheduled

public void algorithmScheduled(Algorithm algorithm,
                               Calendar time)

Description copied from interface: SchedulerListener

Notification that an Algorithm has been scheduled to be run at a certain time

Specified by:

algorithmScheduled in interface SchedulerListener

Parameters:

algorithm - The scheduled Algorithm

time - The time is scheduled to be run

algorithmStarted

public void algorithmStarted(Algorithm algorithm)

Description copied from interface: SchedulerListener

Notification that an Algorithm has started execution

Specified by:

algorithmStarted in interface SchedulerListener

Parameters:

algorithm - The scheduled algorithm

schedulerCleared

public void schedulerCleared()

Description copied from interface: SchedulerListener

Notification that the scheduler's schedule of Algorithms to be run has been cleared

Specified by:

schedulerCleared in interface SchedulerListener

schedulerRunStateChanged

public void schedulerRunStateChanged(boolean isRunning)

Description copied from interface: SchedulerListener

Notification that the scheduler's run state (paused or unpaused) has changed

Specified by:

schedulerRunStateChanged in interface SchedulerListener

Parameters:

isRunning - true if it is now running, false if it is no longer running (paused)
