public class OSDelegatingFileTailingMessageProducer extends FileTailingMessageProducerSupport implements org.springframework.scheduling.SchedulingAwareRunnable
A file tailing message producer that delegates to the OS tail program. This is likely the most efficient mechanism on platforms that support it. Default options are "-F -n 0" (follow file name, no existing records).
