Method Details

start

@ManagedOperation(value="Starts the instance",
                  impact="ACTION")
void start()
    throws Exception

Starts the component.

Throws:

Exception - If the component fails to start

See Also:

• isStarted()
• stop()
• isFailed()

stop

@ManagedOperation(value="Stops the instance",
                  impact="ACTION")
void stop()
   throws Exception

Stops the component. The component may wait for current activities to complete normally, but it can be interrupted.

Throws:

Exception - If the component fails to stop

See Also:

• isStopped()
• start()
• isFailed()

isRunning

boolean isRunning()

Returns:

true if the component is starting or has been started.

isStarted

boolean isStarted()

Returns:

true if the component has been started.

See Also:

• start()
• isStarting()

isStarting

boolean isStarting()

Returns:

true if the component is starting.

See Also:

• isStarted()

isStopping

boolean isStopping()

Returns:

true if the component is stopping.

See Also:

• isStopped()

isStopped

boolean isStopped()

Returns:

true if the component has been stopped.

See Also:

• stop()
• isStopping()

isFailed

boolean isFailed()

Returns:

true if the component has failed to start or has failed to stop.

addLifeCycleListener

void addLifeCycleListener(LifeCycle.Listener listener)

removeLifeCycleListener

void removeLifeCycleListener(LifeCycle.Listener listener)

start

static void start(Object object)

Utility to start an object if it is a LifeCycle and to convert any exception thrown to a RuntimeException

Parameters:

object - The instance to start.

Throws:

RuntimeException - if the call to start throws an exception.

stop

static void stop(Object object)

Utility to stop an object if it is a LifeCycle and to convert any exception thrown to a RuntimeException

Parameters:

object - The instance to stop.

Throws:

RuntimeException - if the call to stop throws an exception.
