* fashion as opposed to the declarative approach of using the
* {@link Scheduled @Scheduled} annotation. For example, this may be necessary
* when implementing {@link org.springframework.scheduling.Trigger Trigger}-based
* tasks, which are not supported by the {@code @Scheduled} annotation.
*
* See {@link EnableScheduling @EnableScheduling} for detailed usage examples.
