public interface Lifecycle

Defines a common interface for component life cycle methods. Any managed component that needs to be started, and stopped during it's lifetime may implement this interface. It is up to the associated manager to invoke these methods.

Since:

12/1/01

Field Summary

static String	START_EVENT The LifecycleEvent type for the "component start" event.
static String	STOP_EVENT The LifecycleEvent type for the "component stop" event.

Method Summary

void	addLifecycleListener(LifecycleListener listener) Add a LifecycleEvent listener to this component.
boolean	isStarted() Determine if the implementing Lifecycle object has been started.
void	removeLifecycleListener(LifecycleListener listener) Remove a LifecycleEvent listener from this component.
void	start() Prepare for the beginning of active use of the public methods of this component.
void	stop() Gracefully terminate the active use of the public methods of this component.

Method Detail

addLifecycleListener

public void addLifecycleListener(LifecycleListener listener)

Add a LifecycleEvent listener to this component.

Parameters:

listener - The listener to add

removeLifecycleListener

public void removeLifecycleListener(LifecycleListener listener)

Remove a LifecycleEvent listener from this component.

Parameters:

listener - The listener to remove

start

public void start()
           throws LifecycleException

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.

Throws:

LifecycleException - if this component detects a fatal error that prevents this component from being used

stop

public void stop()
          throws LifecycleException

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.

Throws:

LifecycleException - if this component detects a fatal error that needs to be reported

isStarted

public boolean isStarted()

Determine if the implementing Lifecycle object has been started.

Returns:

true if the Lifecycle object has been started, false otherwise.
