21  * This interface models beans that supports or requires lazy initialization.
22  * When a bean is created, first of all the empty constructor is created and
23  * the the bean properties are set. If a bean requires that its properties have
24  * a proper value when initialization is performed it should implement
25  * <i>LazyInitBean</i>, so that the caller has an opportunity to separately
26  * initialize the bean after its creation, but before using it.<br>
27  * The described mechanism is used in BeanFactory when an instance of the bean
28  * is created. If the bean implements <i>LazyInitBean</i> after creating the bean
29  * the method init() is called.
