ListableBeanFactory

Extension of the {@link BeanFactory} interface 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. BeanFactory implementations that
* preload all their bean definitions (such as XML-based factories) may implement
* this interface.

public interface ListableBeanFactory extends BeanFactory {

    boolean containsBeanDefinition(String beanName);

    int getBeanDefinitionCount();

    String[] getBeanDefinitionNames();

    String[] getBeanNamesForType(ResolvableType type);

    String[] getBeanNamesForType(Class<?> type);

    String[] getBeanNamesForType(Class<?> type, boolean includeNonSingletons, boolean allowEagerInit);

    <T> Map<String, T> getBeansOfType(Class<T> type) throws BeansException;

    <T> Map<String, T> getBeansOfType(Class<T> type, boolean includeNonSingletons, boolean allowEagerInit)
			throws BeansException;

    String[] getBeanNamesForAnnotation(Class<? extends Annotation> annotationType);

    Map<String, Object> getBeansWithAnnotation(Class<? extends Annotation> annotationType) throws BeansException;

    <A extends Annotation> A findAnnotationOnBean(String beanName, Class<A> annotationType)
			throws NoSuchBeanDefinitionException;
