Method Detail

start

public void start()
           throws LifecycleException
Description copied from interface: Lifecycle
Prepare for the beginning of active use of the public methods of this component. This method should be called before any of the public methods of this component are utilized. It should also send a LifecycleEvent of type START_EVENT to any registered listeners.

Description copied from interface: Lifecycle
Gracefully terminate the active use of the public methods of this component. This method should be the last one called on a given instance of this component. It should also send a LifecycleEvent of type STOP_EVENT to any registered listeners.

Specified by:
stop in interface Lifecycle
Throws:
LifecycleException - if this component detects a fatal error that needs to be reported
