public class DefaultListableBeanFactory extends AbstractAutowireCapableBeanFactory implements ConfigurableListableBeanFactory, BeanDefinitionRegistry, Serializable
ListableBeanFactory and
BeanDefinitionRegistry interfaces: a full-fledged bean factory
based on bean definition objects.
Typical usage is registering all bean definitions first (possibly read from a bean definition file), before accessing beans. Bean definition lookup is therefore an inexpensive operation in a local bean definition table, operating on pre-built bean definition metadata objects.
Can be used as a standalone bean factory, or as a superclass for custom
bean factories. Note that readers for specific bean definition formats are
typically implemented separately rather than as bean factory subclasses:
see for example PropertiesBeanDefinitionReader and
XmlBeanDefinitionReader.
For an alternative implementation of the
ListableBeanFactory interface,
have a look at StaticListableBeanFactory, which manages existing
bean instances rather than creating new ones based on bean definitions.

Depending on the nature of the concrete bean factory implementation, this operation might be expensive (for example, because of directory lookups in external registries). However, for listable bean factories, this usually just amounts to a local hash lookup: The operation is therefore part of the public interface there. The same implementation can serve for both this template method and the public interface method in that case.

SingletonBeanRegistryThe given instance is supposed to be fully initialized; the registry
will not perform any initialization callbacks (in particular, it won't
call InitializingBean's afterPropertiesSet method).
The given instance will not receive any destruction callbacks
(like DisposableBean's destroy method) either.
When running within a full BeanFactory: Register a bean definition instead of an existing instance if your bean is supposed to receive initialization and/or destruction callbacks.
Typically invoked during registry configuration, but can also be used for runtime registration of singletons. As a consequence, a registry implementation should synchronize singleton access; it will have to do this anyway if it supports a BeanFactory's lazy initialization of singletons.

The default implementation delegates to the specified
dependency comparator, checking its
method if it is an extension of
Spring's common OrderComparator - typically, an
AnnotationAwareOrderComparator.
If no such comparator is present, this implementation returns null.
