A typical example: * prioritized post-processors in a Spring * {@link org.springframework.context.ApplicationContext}. * * <p>Note: {@code PriorityOrdered} post-processor beans are initialized in * a special phase, ahead of other post-processor beans. This subtly * affects their autowiring behavior: they will only be autowired against * beans which do not require eager initialization for type matching. * * @author Juergen Hoeller * @since 2.5 * @see org.springframework.beans.factory.config.PropertyOverrideConfigurer * @see org.springframework.beans.factory.config.PropertyPlaceholderConfigurer */ public interface PriorityOrdered extends Ordered { }
