Class SimpleTimeBroker

  • All Implemented Interfaces:
    TimeBroker

    public class SimpleTimeBroker
    extends java.lang.Object
    implements TimeBroker

    The interface to be implemented by classes that want to provide a mechanism by which the QuartzScheduler can reliably determine the current time.

    In general, the default implementation of this interface (SimpleTimeBroker- which simply uses System.getCurrentTimeMillis() )is sufficient. However situations may exist where this default scheme is lacking in its robustsness - especially when Quartz is used in a clustered configuration. For example, if one or more of the machines in the cluster has a system time that varies by more than a few seconds from the clocks on the other systems in the cluster, scheduling confusion will result.

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      java.util.Date getCurrentTime()
      Get the current time, simply using new Date().
      void initialize()
      Called by the QuartzScheduler before the TimeBroker is used, in order to give the it a chance to initialize.
      void shutdown()
      Called by the QuartzScheduler to inform the TimeBroker that it should free up all of it's resources because the scheduler is shutting down.
