package org.springframework.context;

import org.springframework.beans.BeansException;

 * Interface to be implemented by any object that wishes to be notified
 * of the {@link ApplicationContext} that it runs in.
 * <p>Implementing this interface makes sense for example when an object
 * requires access to a set of collaborating beans. Note that configuration
 * via bean references is preferable to implementing this interface just
 * for bean lookup purposes.
 * <p>This interface can also be implemented if an object needs access to file
 * resources, i.e. wants to call <code>getResource, wants to publish
 * an application event, or requires access to the MessageSource. However,
 * it is preferable to implement the more specific {@link ResourceLoaderAware},
 * {@link ApplicationEventPublisherAware} or {@link MessageSourceAware} interface
 * in such a specific scenario.
 * <p>Note that file resource dependencies can also be exposed as bean properties
 * of type {@link org.springframework.core.io.Resource}, populated via Strings
 * with automatic type conversion by the bean factory. This removes the need
 * for implementing any callback interface just for the purpose of accessing
 * a specific file resource.
 * <p>{@link org.springframework.context.support.ApplicationObjectSupport} is a
 * convenience base class for application objects, implementing this interface.
 * <p>For a list of all bean lifecycle methods, see the
 * {@link org.springframework.beans.factory.BeanFactory BeanFactory javadocs}.

	 * Normally this call will be used to initialize the object.
	 * <p>Invoked after population of normal bean properties but before an init callback such
	 * as {@link org.springframework.beans.factory.InitializingBean#afterPropertiesSet()}
	 * or a custom init-method. Invoked after {@link ResourceLoaderAware#setResourceLoader},
	 * {@link ApplicationEventPublisherAware#setApplicationEventPublisher} and
	 * {@link MessageSourceAware}, if applicable.
	 * @param applicationContext the ApplicationContext object to be used by this object
	 * @throws ApplicationContextException in case of context initialization errors
	 * @throws BeansException if thrown by application context methods
