All Implemented Interfaces:

MuleContextAware

Direct Known Subclasses:

FixedFrequencySchedulerFactory

public abstract class SchedulerFactory<T extends Runnable>
extends Object
implements MuleContextAware

Factory of schedulers. Every Scheduler should be created by a SchedulerFactory if the creation process allows post creation hooking.

Once the Factory creates a scheduler it calls a set of SchedulerFactoryPostProcessor that might affect the instance of the scheduler.

The SchedulerFactory also registers the Scheduler into the mule registry.

Since:

3.5.0
