/**
* Extension of the {@link Ordered} interface, expressing a 'priority'
* ordering: Order values expressed by PriorityOrdered objects always
* apply before order values of 'plain' Ordered values.
*
* <p>This is primarily a special-purpose interface, used for objects
* where it is particularly important to determine 'prioritized'
* objects first, without even obtaining the remaining objects.
* A typical example: Prioritized post-processors in a Spring
* {@link org.springframework.context.ApplicationContext}.
*
* <p>Note: 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.
