org.springframework.core.OrderComparator
- All Implemented Interfaces: 
- Comparator
- Direct Known Subclasses: 
- AnnotationAwareOrderComparator
- public class OrderComparator 
- extends Object- implements Comparator
Comparator implementation for Ordered objects,
 sorting by order value ascending (resp. by priority descending).
 
Non-Ordered objects are treated as greatest order
 values, thus ending up at the end of the list, in arbitrary order
 (just like same order values of Ordered objects).
