package org.springframework.core;

 Interface that can be implemented by objects that should be
 orderable, for example in a Collection.

 The actual order can be interpreted as prioritization, with
 the first object (with the lowest order value) having the highest
 priority.

 
Note that there is a 'priority' marker for this interface:
 PriorityOrdered. Order values expressed by PriorityOrdered
 objects always apply before order values of 'plain' Ordered values.

 Useful constant for the lowest precedence value.

	int LOWEST_PRECEDENCE = Integer.MAX_VALUE;


	
 Return the order value of this object, with a
 higher value meaning greater in terms of sorting.
 Normally starting with 0, with Integer.MAX_VALUE
 indicating the greatest value. Same order values will result
 in arbitrary positions for the affected objects.
 
Higher values can be interpreted as lower priority. As a
 consequence, the object with the lowest value has highest priority
 (somewhat analogous to Servlet "load-on-startup" values).
