Field Detail

activeSchedulers

protected Map<UUID,org.quartz.Scheduler> activeSchedulers

Contains running plugin instances. The key is the associated random UUID. This is needed to correctly stop the running plugin execution if the container is stopped in the proper way

Method Detail

getInstance

                                              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

Returns:

the created scheduler

Throws:

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

                     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
