org.quartz.spi: public interface: TimeBroker

org.quartz.spi
public interface: TimeBroker [javadoc | source]

All Known Implementing Classes:
SimpleTimeBroker

Deprecated! TimeBroker - is not currently used in the Quartz code base.

NOTE: TimeBroker is not currently used in the Quartz code base.

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

In general, the default implementation of this interface (org.quartz.simpl.SimpleTimeBroker - which simply uses System.getCurrentTimeMillis() )is sufficient. However situations may exist where this default scheme is lacking in its robustness - 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.

Method from org.quartz.spi.TimeBroker Summary:
getCurrentTime, initialize, shutdown

Method from org.quartz.spi.TimeBroker Detail:
public Date getCurrentTime() throws SchedulerException Deprecated! Get the current time, as known by the `TimeBroker`.
public void initialize() throws SchedulerConfigException Deprecated! Called by the QuartzScheduler before the `TimeBroker` is used, in order to give the it a chance to initialize.
public void shutdown() Deprecated! Called by the QuartzScheduler to inform the `TimeBroker` that it should free up all of it's resources because the scheduler is shutting down.
