Description

Interface Summary

BeanFactory	Interface to be implemented by objects that hold a number of bean definitions, each uniquely identified by a String name.
FactoryBean	Interface to be implemented by objects used within a BeanFactory that are themselves factories.
InitializingBean	Interface to be implemented by beans that need to react once all their properties have been set by a BeanFactory: for example, to perform initialization, or merely to check that all mandatory properties have been set.
Lifecycle	Interface to be implemented by beans that wish to be notified of lifecycle events by their owning BeanFactory.
ListableBeanFactory	Extension of BeanFactory to be implemented by bean factories that can enumerate all their bean instances, rather than attempting bean lookup by name one by one as requested by clients.

Exception Summary

BeanDefinitionStoreException	Exception thrown when a BeanFactory encounters an internal error, and its definitions are invalid: for example, if an XML document containing bean definitions isn't well-formed.
BeanIsNotAFactoryException	Exception thrown when a bean is not a factory, but a user tries to get at the factory for the given bean name.
BeanNotOfRequiredTypeException	Thrown when a bean doesn't match the required type
NoSuchBeanDefinitionException	Exception thrown when a BeanFactory is asked for a bean instance name for which it cannot find a definition.
