Package org.jbpm.process.core.timer

Interface GlobalSchedulerService

  • All Superinterfaces:
    org.drools.core.time.InternalSchedulerService, org.drools.core.time.SchedulerService
    All Known Implementing Classes:
    QuartzSchedulerService, ThreadPoolSchedulerService
    public interface GlobalSchedulerService
extends org.drools.core.time.SchedulerService, org.drools.core.time.InternalSchedulerService
    Implementations of these interface are responsible for scheduled jobs in global manner, meaning not knowledge session scoped but global accessible for all the sessions that will be configured to use this GlobalSchedulerService
