    /**
     * 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
