public class: ContextBeanFactoryReference [javadoc | source]

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

All Implemented Interfaces:
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.
