Class DefaultLifecycleAdapter

java.lang.Object
  org.mule.component.DefaultLifecycleAdapter

All Implemented Interfaces:

LifecycleAdapter, Disposable, Initialisable, Lifecycle, Startable, Stoppable

Direct Known Subclasses:

NullLifecycleAdapter

public class DefaultLifecycleAdapter
extends Object
implements LifecycleAdapter

DefaultLifecycleAdapter provides lifecycle methods for all Mule managed components. It's possible to plugin custom lifecycle adapters, this can provide additional lifecycle methods triggered by an external source.

Method Detail

start

public void start()
           throws MuleException

Propagates start() life-cycle to component object implementations if they implement the mule Startable interface. NOT: It is up to component implementations to ensure their implementation of start() is thread-safe.

Specified by:

start in interface Startable

Throws:

MuleException

stop

public void stop()
          throws MuleException

Propagates stop() life-cycle to component object implementations if they implement the mule Stoppable interface. NOT: It is up to component implementations to ensure their implementation of stop() is thread-safe.

Specified by:

stop in interface Stoppable

Throws:

MuleException

dispose

public void dispose()

Propagates dispose() life-cycle to component object implementations if they implement the mule Disposable interface. NOT: It is up to component implementations to ensure their implementation of dispose() is thread-safe.

Specified by:

dispose in interface Disposable

isStarted

public boolean isStarted()

Specified by:

isStarted in interface LifecycleAdapter

Returns:

true if the service has been started

isDisposed

public boolean isDisposed()

Specified by:

isDisposed in interface LifecycleAdapter

Returns:

whether the service managed by this lifecycle has been disposed

invoke

public Object invoke(MuleEvent event)
              throws MuleException

Specified by:

invoke in interface LifecycleAdapter

Throws:

MuleException

initialise

public void initialise()
                throws InitialisationException

Propagates initialise() life-cycle to component object implementations if they implement the mule Initialisable interface.

NOTE: It is up to component implementations to ensure their implementation of initialise() is thread-safe.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

configureBinding

protected void configureBinding()
                         throws MuleException

Throws:

MuleException

createRegistryHardRefName

protected String createRegistryHardRefName(Component component)

Generate a registry key name for this component. Used to bind component's hard reference to the Mule's lifecycle and prevent the garbage collector from kicking in too early.

Parameters:

component - component to generate the name for

Returns:

registry key name
