getTriggerBuilderWithScheduling

protected org.quartz.TriggerBuilder<? extends org.quartz.Trigger> getTriggerBuilderWithScheduling(UUID uuid,
                                                                                                  org.gcube.vremanagement.executor.api.types.Scheduling scheduling)
                                                                                           throws org.gcube.vremanagement.executor.exception.LaunchException

Throws:

org.gcube.vremanagement.executor.exception.LaunchException

reallySchedule

protected void reallySchedule(UUID uuid,
                              org.gcube.vremanagement.executor.api.types.LaunchParameter parameter)
                       throws org.gcube.vremanagement.executor.exception.LaunchException,
                              org.quartz.SchedulerException

Create the Scheduler using the strategy provided by LaunchParameter

Parameters:

uuid - the UUID will be used to identify the task

parameter - LaunchParameter requested in service invocation

Throws:

org.gcube.vremanagement.executor.exception.LaunchException - if the LaunchParameter does not contains a valid scheduling strategy

org.quartz.SchedulerException - if the scheduler cannot be created by the scheduler factory

schedule

public UUID schedule(org.gcube.vremanagement.executor.api.types.LaunchParameter parameter,
                     UUID uuid)
              throws org.gcube.vremanagement.executor.exception.InputsNullException,
                     org.gcube.vremanagement.executor.exception.PluginNotFoundException,
                     org.gcube.vremanagement.executor.exception.LaunchException

Schedule a task execution

Parameters:

parameter - LaunchParameter requested in service invocation

Returns:

the UUID which will identify the task

Throws:

org.gcube.vremanagement.executor.exception.LaunchException - if the LaunchParameter does not contains a valid scheduling strategy

org.gcube.vremanagement.executor.exception.InputsNullException - if provided input map is null

org.gcube.vremanagement.executor.exception.PluginNotFoundException - if the request plugin is not available on this smart executor instance

stopTask

protected void stopTask(UUID uuid)
                 throws org.gcube.vremanagement.executor.exception.UnableToInterruptTaskException

Throws:

org.gcube.vremanagement.executor.exception.UnableToInterruptTaskException

getCurrentlyExecutingJobs

protected List<org.quartz.JobExecutionContext> getCurrentlyExecutingJobs(org.quartz.Scheduler scheduler)
                                                                  throws org.quartz.SchedulerException

Throws:

org.quartz.SchedulerException

getLaunchParameter

Throws:

org.quartz.SchedulerException

stop

public void stop(UUID uuid,
                 boolean remove)
          throws Exception

Stop the execution of the Task identified by UUID

Parameters:

uuid - which identify the Task
