package org.springframework.beans.factory;

import org.springframework.beans.BeansException;

Interface to be implemented by beans that wish to be aware of their owning BeanFactory. 
For example, beans can look up collaborating beans via the factory
(Dependency Lookup). Note that most beans will choose to receive references
to collaborating beans via corresponding bean properties or constructor
arguments (Dependency Injection).
For a list of all bean lifecycle methods, see the BeanFactory javadocs.

Callback that supplies the owning factory to a bean instance.
Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method. 
Params:
beanFactory – owning BeanFactory (never null). The bean can immediately call methods on the factory.
Throws:
BeansException – in case of initialization errors
