Interface PriorityOrdered

All Superinterfaces:
Ordered
All Known Implementing Classes:

public interface PriorityOrdered
extends Ordered

Extension of the Ordered interface, expressing a 'priority' ordering: Order values expressed by PriorityOrdered objects always apply before order values of 'plain' Ordered values.

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 ApplicationContext.

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.
