public class AStarHeapComparator<NODE>
extends Object
implements Comparator

This comparator is a tricky object - it serves for the AStarHeap to compare nodes inside the heap.

The trick is, that it is initialized AStarHeapComparator(Map) with a map that contains node's costs that are used during the comparation inside compare(Object, Object). No magic yet, ha? Well, the magic is that this map is not cloned... simply a pointer to this very instance passed inside the constructor is saved to you may alter the cost as you wish to! Which is truly needed by the AStar class that is obtaining nodes' costs from the AStarMap implementor.
