## 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`

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `org.drools.core.time.JobHandle` | `buildJobHandleForContext(NamedJobContext ctx)` Builds JobHandle based on NamedJobContext
    `void` | `initScheduler(org.drools.core.time.TimerService timerService)` Provides handle to inject timerService that owns this scheduler service and initialize it
    `boolean` | `isTransactional()` Indicates if given implementation of scheduler service supports transactional timer store.
    `boolean` | `isValid(GlobalTimerService.GlobalJobHandle jobHandle)` Verifies if given job is still valid or it was already executed/vetoed.
    `boolean` | `retryEnabled()` Indicates if given implementation of scheduler service supports retries of failed timer jobs
    `void` | `setInterceptor(SchedulerServiceInterceptor interceptor)` Allows to set interceptor that will be used to schedule timer instances
    `void` | `shutdown()` Allows to shutdown the scheduler service

    - #### initScheduler

          void initScheduler(org.drools.core.time.TimerService timerService)

      Provides handle to inject timerService that owns this scheduler service and initialize it
      Parameters:
        `timerService` - owner of this scheduler service

    - #### shutdown

          void shutdown()

      Allows to shutdown the scheduler service

    - #### buildJobHandleForContext

          org.drools.core.time.JobHandle buildJobHandleForContext(NamedJobContext ctx)

      Builds JobHandle based on NamedJobContext
      Parameters:
        `ctx` -
      Returns:

    - #### isTransactional

          boolean isTransactional()

      Indicates if given implementation of scheduler service supports transactional timer store.
      Returns:

    - #### retryEnabled

          boolean retryEnabled()

      Indicates if given implementation of scheduler service supports retries of failed timer jobs
      Returns:

    - #### setInterceptor

          void setInterceptor(SchedulerServiceInterceptor interceptor)

      Allows to set interceptor that will be used to schedule timer instances
      Parameters:
        `interceptor` -

    - #### isValid

          boolean isValid(GlobalTimerService.GlobalJobHandle jobHandle)

      Verifies if given job is still valid or it was already executed/vetoed. Especially important in multi node environments - cluster.
      Parameters:
        `jobHandle` -
      Returns:
