public interface SuspendableService
extends Service

A Service which is also capable of suspending and resuming.

This is useable for services which needs more fine grained control at runtime supporting suspension. Other services may select to mimic suspending by just stopping the service.

For example this is use by the JmsConsumer which suspends the Spring JMS listener instead of stopping the consumer totally.

Method Summary
