	/**
	 * Return an instance, which may be shared or independent, of the specified
	 * bean.
	 * <p>
	 * This method allows a Spring BeanFactory to be used as a replacement for
	 * the Singleton or Prototype design pattern. Callers may retain references
	 * to returned objects in the case of Singleton beans.
	 * <p>
	 * Translates aliases back to the corresponding canonical bean name. Will
	 * ask the parent factory if the bean cannot be found in this factory
	 * instance.
	 * 
	 * @param name
	 *            the name of the bean to retrieve
	 * @return an instance of the bean
	 * @throws NoSuchBeanDefinitionException
	 *             if there is no bean definition with the specified name
	 * @throws BeansException
	 *             if the bean could not be obtained
