public interface Lifecycle

Interface defining methods for start/stop lifecycle control. The typical use case for this is to control asynchronous processing.

Can be implemented by both components (typically a Spring bean defined in a Spring BeanFactory) and containers (typically a Spring ApplicationContext). Containers will propagate start/stop signals to all components that apply.

Can be used for direct invocations or for management operations via JMX. In the latter case, the MBeanExporter will typically be defined with an InterfaceBasedMBeanInfoAssembler, restricting the visibility of activity-controlled components to the Lifecycle interface.

Method Summary

boolean isRunning()
          Check whether this component is currently running.

void start()
          Start this component.

void stop()
          Stop this component.

Method Summary
`boolean`	`isRunning()` Check whether this component is currently running.
`void`	`start()` Start this component.
`void`	`stop()` Stop this component.

Method Detail

start

void start()

Start this component. Should not throw an exception if the component is already running.

In the case of a container, this will propagate the start signal to all components that apply.

stop

void stop()

Stop this component. Should not throw an exception if the component isn't started yet.

In the case of a container, this will propagate the stop signal to all components that apply.

isRunning

boolean isRunning()

Check whether this component is currently running.

In the case of a container, this will return true only if all components that apply are currently running.

Returns:: whether the component is currently running
