更新Java PriorityQueue时，其元素更改优先级(Updating Java PriorityQueue when its elements change priority)

 我试图使用PriorityQueue来使用Comparator来对对象进行排序。 
 
 这可以很容易地实现，但是对象类变量（比较器计算优先级）可以在初始插入之后改变。 大多数人建议删除对象，更新值并重新插入该对象的简单解决方案，因为优先级队列的比较器将被执行。 
 
 除了在PriorityQueue周围创建一个包装类来做这个吗？ 

I'm trying to use a PriorityQueue to order objects using a Comparator.
 
This can be achieved easily, but the objects class variables (with which the comparator calculates priority) may change after the initial insertion. Most people have suggested the simple solution of removing the object, updating the values and reinserting it again, as this is when the priority queue's comparator is put into action.
 
Is there a better way other than just creating a wrapper class around the PriorityQueue to do this?
