org.springframework.context.access
Class ContextBeanFactoryReference

java.lang.Object
  org.springframework.context.access.ContextBeanFactoryReference

All Implemented Interfaces:

BeanFactoryReference

---

public class ContextBeanFactoryReference
extends Object
implements BeanFactoryReference

ApplicationContext-specific implementation of BeanFactoryReference, wrapping a newly created ApplicationContext, closing it on release.

As per BeanFactoryReference contract, release may be called more than once, with subsequent calls not doing anything. However, calling getFactory after a release call will cause an exception.

13.02.2004

Constructor Detail

ContextBeanFactoryReference

public ContextBeanFactoryReference(ApplicationContext applicationContext)

Create a new ContextBeanFactoryReference for the given context.

Parameters:

applicationContext - the ApplicationContext to wrap

Method Detail

getFactory

public BeanFactory getFactory()

Description copied from interface: BeanFactoryReference

Return the BeanFactory instance held by this reference.

Specified by:

getFactory in interface BeanFactoryReference

---

release

public void release()

Description copied from interface: BeanFactoryReference

Indicate that the BeanFactory instance referred to by this object is not needed any longer by the client code which obtained the BeanFactoryReference.

Depending on the actual implementation of BeanFactoryLocator, and the actual type of BeanFactory, this may possibly not actually do anything; alternately in the case of a 'closeable' BeanFactory or derived class (such as ApplicationContext) may 'close' it, or may 'close' it once no more references remain.

In an EJB usage scenario this would normally be called from ejbRemove() and ejbPassivate().

This is safe to call multiple times.

Specified by:

release in interface BeanFactoryReference
