Class PooledJavaComponent.LifeCycleAdaptorFactory

java.lang.Object

org.mule.component.PooledJavaComponent.LifeCycleAdaptorFactory

All Implemented Interfaces:

Disposable, Initialisable, ObjectFactory

Enclosing class:

PooledJavaComponent

protected class PooledJavaComponent.LifeCycleAdaptorFactory
extends Object
implements ObjectFactory

LifeCycleAdaptorFactory wraps the Component' s ObjectFactory. The LifeCycleAdaptorFactory "getInstance()" method creates a new LifecycleAdapter wrapping the object instance obtained for the component instance ObjectFactory set on the Component.
This allows us to keep LifecycleAdapter creation in the Component and out of the DefaultLifecyleEnabledObjectPool and to use the generic ObjectPool interface.

Method Detail

getInstance

public Object getInstance()
                   throws Exception

Description copied from interface: ObjectFactory

Retrieve an instance of the object. This may create a new instance or look up an existing instance depending on the implementation. If a new instance is created it will also be initialized by this method (Initilisable.initialise()).

Specified by:

getInstance in interface ObjectFactory

Throws:

Exception

getObjectClass

public Class getObjectClass()

Description copied from interface: ObjectFactory

Returns the class of the object to be instantiated without actually creating an instance. This may not be logical or even possible depending on the implementation.

Specified by:

getObjectClass in interface ObjectFactory

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

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

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

Specified by:

dispose in interface Disposable

addObjectInitialisationCallback

public void addObjectInitialisationCallback(InitialisationCallback callback)

Description copied from interface: ObjectFactory

Register a custom initialiser

Specified by:

addObjectInitialisationCallback in interface ObjectFactory

isSingleton

public boolean isSingleton()

Description copied from interface: ObjectFactory

Returns true if the ObjectFactory implementation always returns the same object instance.

Specified by:

isSingleton in interface ObjectFactory

Returns:
